I have two things to say: 1- Genius. 2- Seems like the byte saving is minimum. At this point, a regular if would take exactly the same amount of code when minified (plus the .end()'s) and it makes it harder to read, specially for non- chaining-addicts (not my case).
In short, I love the idea, but doesn't seem so useful in the end.
