That's your logic, not necessarily that of others.  There's no
"M-y M-y" with a preceding C-y, so I don't see any problem in the
current behavior: it can be easily described in the documentation, and
feels natural to me.

But if you want to change it to the behavior you expect, I don't mind.
Just do that (and the setting of the kill-ring pointer) soon, because
currently the documentation of the new behavior of M-y in the manual
is incomplete, and I'd like to complete it before I forget.

Thanks.
