As far as I know, it doesn't.  If a changeset modifies a file, I don't
believe the extension checks to see whether it's a merge changeset or
not.  The file is checked solely based upon its name.

I think that the merge would currently not be allowed to be pushed.  It
would be straightforward to check each file in a merge to see whether
it's the same as in one of the parents of the merge, though this is not
obviously desirable.  The current strategy, conservative as it is, is
arguably better from an access control point of view: you can't mess in
any way with the history of a file to which you don't have push access.
