Hmm... I think you can turn it off generally with something like

zstyle ':completion::complete:-tilde-::' tag-order named-directories

(allow named directories but not usernames), but so far as I know
there's no way of doing it just after cdr.  The problem is the context
here is a special one, "-tilde-", which replaces the normal command
context, so it no longer cares.  This happens early enough that none of
the special code to do with cdr is ever run.

I don't think it's that difficult to rejig the context in _tilde, which
isn't a particularly big function, so that it does care, by extracting
$words[1] from the command line and sticking it appropriately in the
context.  For example, replace the -tilde- with -tilde-$words[1].  I
haven't tried this --- and although it's useful it will break
compatibility with anyone trying to do this sort of thing for all
commands, so you might be better off just experimenting locally.
