Hmm, it's true that one common feature of both of these languages is that they traditionally use process images. That's not required, though, and every Lisp program over 100 lines I've seen written in the past 25 years has used a normal text-based version control system. Also, while bypassing version control and doing everything in-process can be a great productivity boon for a single programmer, even a team of 2 has outgrown that. This wouldn't explain why (he thinks) these languages work for small teams but not larger teams.
