It's because of the cardioid pattern. I think how the proximity effect
works is discussed in the FAQ. I know there was a long discussion of
this here a couple years ago.
EV used to also have a nice discussion of this on the glossy sheet for
"C'est un Nagra. C'est suisse, et tres, tres precis."

I'd thought this too but came to wonder why the effect, as
described, would be at all frequency dependant.
