F-antenna of MC213x reference design

I'm new to antenna design and I don't pretend to know a thing that I'm talking about. I'm basing my own design on the reference in AN3248 with some success ... but the F-antenna is puzzling me.

After reading up on the subject, I'm wondering why the antenna exists on both layers of the board. Is there a reason why the entire ground plane should just be extended into this region?

Of course, I don't have a physical reference board, so I'm just basing this on what I see in the .pdf file.
