This is unrelated to the bug Bart pointed to. I can't reproduce what you
show exactly but I have isolated this down to what is undoubtably a bug.
Whether this is the problem you're having, I'm not sure.

I always found that sort of stuff (filling in characters to the right of
the cursor) a bit weird. I've seen it before and assumed Sven meant it
as a feature. Maybe he didn't.

We can cut this down to a minimal setup to see problems:

zsh -f
autoload -U compinit; compinit
zstyle ':completion:*:::' _complete
_try() {       
compset -P '*@'
compadd -M 'r:|.=* r:|=*' \
        yupa-dmz.valley-of-wind.krose.org \
        yupa.krose.org yupa.valley-of-wind.krose.org
}
compdef _try t

Now compare the following:
% t y<tab>
  -> t yupa_
% t kr@y<tab>
  -> t kr@yupa_
% t kro@y<tab>
  -> t kro@yupa._.

Where _ is the cursor.

Patterns like '???' and '????' in compset also work. If compset has
removed four or more characters, we get the separator character (.)
inserted. So the problem is in the C code.

I fiddled with this just a little.  It's not always "four or more" --
it's somehow related to the length of the (un?)ambiguous prefix in the
part compset leaves behind.  For example, if you change
	yupa-dmz.valley-of-wind.krose.org
to
	yuppa-dmz.valley-of-wind.krose.org
in your minimal example (extra 'p'), then the problem appears only
after compset has removed five or more characters.  If you change the
set of completions to
	yupa-dmz.valley-of-wind.krose.org \ 
	yipa.krose.org yopa.valley-of-wind.krose.org
then the problem appears only after seven or more characters are
removed.  And you can see it with

% t 123456@y

so it's not related to "kro" forming a substring of the right side.
