Were both of these using the same Dovecot version or was the second one
different?

In both of the cases Dovecot's replies to these 3 commands were
identical. So why did the client decide to do RETR only in the second
session?.. I don't really have any ideas what could be the problem.

If you can easily test this, I guess the best way would be to find one
which Dovecot v1.0.x version exactly broke this for you (and after that
which hg commit change broke it).
