That’s not really possible unless it wasn't uninstalled, it would have had to do the same things both times if it were really installing it both times, obviously. It’s the same operation.

The flag means that the file can be absent but the module would still consider itself installed. It has nothing to do with overwrite semantics, that's handled by a different property (replace).

As far as I know that would be impossible since the starting point would be the same in both cases, which means the starting point wasn't in fact the same in both cases. 

My guess is it's a bug related to there being only one resource, marked optional, and it's confusing the operations it's performing.
