Yes, that is what happens now. GnuPG automatically strips an older
self signature if a newer valid self signature is already available.
On the other hand, a newer self signature is accepted for import, but
the old one is not deleted. This is occasionally reported as a bug.
It isn't a bug, but it can be confusing.
It is a very good thing that the keyservers do not do this since they
do not have cryptographic support to know whether the "new" signature
is valid (or indeed, whether it is really new or not).
