100% agree. I managed a similar MCAT score to his without ever taking a science class. If you are a good test taker, the MCAT is totally doable. Maybe not a 40+, but mid 30s totally.
I think Step 1 can be either/or and it simply depends on the person. A 260+ with just memorization is only possible if you are an absolute rockstar of memorizing. I have a buddy who did just that as well, an absolute beast of a memory and the fastest test-taker I've met, finished Step 1 2-3 hours early. I'm more a "big picture" learn the concepts kind of person who used every second of his step 1 time to get the exact same score he did. To me, it wasn't memorization at all, merely applying the concepts I already knew and understood.
So, lots of roads to Oz, but anyone in the 260+ range is probably more naturally gifted AND worked harder than most; as such, their advice should be taken with a grain of salt.
