I haven't checked this by experiment, but reading the code of Exim 4.20
shows that it doesn't send RSET if there's a timeout after RCPT. It just
closes the socket. The only time Exim sends RSET is when it is about to
try to send another message on the same connection, after the previous
one was aborted (e.g. all recipients rejected).

Er, hang on. You are talking about callouts here. They are a bit
different ... read, read, read ... ah, yes, the code is different there.
It really should pay some attention to the timeout, I think. It
currently doesn't, exactly as you suggest.

No apology needed, I picked up the wrong end! I think you have diagnosed
an infelicity in the code. I'll do something about it in due course.

Thanks,
