Yes.

save-excursion doesn't work by saving a character number, but setting a
marker at the old point-location, and restoring to the marker later.

If you insert or delete text adjacent to a marker, it will end up shoved
to one side or the other -- and transpose-lines works by deleting and
inserting.
