Makes sense - this is consistent with the docs, thanks! LGTM

> I'm not quite sure of the complete solution for this issue. But the same problem might also happen to other vector transformations which require to insert ops before/after a maskable vector op. Any feedback will be very helpful : )

In my view, we should try to make sure that we use every opportunity possible to drop the unit dims at **higher levels** of abstraction  - to avoid the problem to begin with. Further down things become tricky.
