I call your example the biggest misconception about match that students have. I'm not trying to harass you, but students enter the match each year and think it works the way you describe. In the example you give, the student is at ZERO disadvantage by putting Univ of Fake at the bottom of his list even with the phone call from the Univ saying "Put us first! We're putting you first!" Univ of Fake has the student in their #1 spot. The student gets this call but puts Univ of Fake at the bottom of his list, his #5 spot, b/c he didn't really like them as much as his other interviews. Match runs its algorithm, tries to place the student into his #1 - 4 choices and can't b/c those schools hated the guy so much they didn't even put him on their lists. So match hits #5 on the student's list, Univ of Fake. Then match looks at Univ of Fake's list and sees the student at #1 on their list. Bingo, a "match" has been made and the student ends up at Univ of Fake anyways. If any of the schools at #1 - 4 had actually like the guy and put him in their #1 spot, he would have matched at that position and the computer wouldn't have even reached the # 5 Univ of Fake entry on his list. They would have lost him regardless of what they told him in a post-interview phone call. So in this case, UCLA is not getting their top choice by entering through the match. This is all explained in the match website in the "how match works examples" or something like that.
So again yes, UCLA is preying on the student b/c if they offer him a spot before match. He doesn't even get to enter match and see if he would have gotten into any of the schools who do play by the match rules.
Did that make sense? It's very hard to explain all this over the net, it's just one of those "aha!"

things about the match that takes a while to understand.
The Match algorithm ALWAYS favors the applicant. This means that if one of the programs you interview with puts you in their #1 spot on their list (like the Univ of Fake was planning to do), then you can arrange your list in ANY order and are GUARANTEED at minimum that come match day you will be in somewhere. It may not be your #1 choice, but you will be in. As long as you don't leave the Univ of Fake off your list, b/c then you would be screwed if no one else wanted you. It happens, people are dumb enough to not rank all their programs and end up with one of those "We're sorry to inform you" e-mails.... That's why a corollary of all this is "Rank every program you interview with."
Yes, programs ask all the time where else you are interviewing. I used to think it was annoying. Then when all the applicants came this year, I realized I had nothing to really talk to them about that would fill a conversation for an entire day and they were all talking about all the other programs they had visited anyways. Some were sitting around discussing that "program x is awesome and my favorite!" not a good thing to say when you are at the program Y interview. Another thing that can be gauged by asking where else you applied/interviewed is to see how serious you really are about ortho - will you give it 100% and train almost anywhere if given the opportunity, or are you only applying to 2 programs because you can't ever imagine leaving your square state for !gasp! another part of the country for a few years. B/c we all know FTDs leave their home countries to come here if given the chance, oh wait, that's another thread.
And there have been stories out there where phone calls have been made saying "We're ranking you high!" and come match day, the student doesn't even match anywhere... maybe it's an urban legend, maybe it was UCLA, haha.
