I agree here with Mark that this is an oversight, an aberration. It should't work the way it presently does, and I would not count on it being this way forever. Some other issue may arise in the future requiring someone to "fix this" and your code will break. 

Swim away from the other fish if you like, but beware of the sharks lurking about.
