Well, I'm sure sure it does happen since the code does it blindly.
The question is whether it makes a difference to the user.  What you have to
keep in mind is that it inserts the text as the "last but one" element, so
just C-y is not affected, it's only the subsequent M-y which is changed.
So the only case which may cause problem is when the user wanted to do C-y
followed by N times M-y where she'd then need to use M-y N+1 times.
