No, not really.  At least it does not seem to be that way.
A bug report quoted above has examples where such problem was
observed.  Look at a sequence of events which follows
"Running Transaction" to see "Removing/Updating" and effects.

If this would happen with packages which do not have config files
then you would not get into any troubles .  The issue appears to be
that "remove" step saves "not-anymore-needed" configuration files
saving them with .rpmsave suffix, but "update" knows that it should
not clobber config files which originally were there so it refrains
from unpacking defaults ones.  That is actually what it _should_ do.
Net effects may turn out to be nasty.

I assume that what Thomas and Julian are talking about is
another manifestation of that bug.  If that is really something
else that would interesting too.
