Throwing in my 2 cent hypotheses.
New traffic rules + New admission policies for DS+ Step 1 pass/fail+ Covid19 have created a difficult situation for DS.
I recall seeing
LizzyM post about how top students being more likely to CTE at higher prestige schools due to step 1 being pass/fail now. All med schools are going to choose top students first, regardless of how plausible it is that they will attend, in order to boost their own prestige. A lot of people write about how they want to serve the underserved and while that may be true, I believe a large portion are only comfortable doing so from within the walls of rich hospitals. Add to that NYC is Covid central. Can you imagine being the head of an adcom and opening up your schools data on May 1st and discovering how few ppl PTE'd to your school?
I hypothesize that the 2024 class is severely underfilled and DS is having severe admin issues due to all of the above reasons. The alt email didnt even have the form we needed to send back. Thus, they sent out alt list positions in order to gauge student's interest so they can offer As more strategically instead of sending them out only to be withdrawn 5 days later. Its already late in the game and having to wait 5 days for each batch of acceptees to decide is going to waste a lot of time. At this point last year, people on alt lists already had to begin acceptance checklists in case they were accepted. I believe the adcom is in a difficult spot right now and trying to keep it together.
Again, all speculation.
