I'm not sure if it was advertised that way, but according to 3com's site:
3Com-patented XJACK antenna design extends for use and retracts for safe
transport and to conserve power; no need to remove the PC Card from the
notebook while traveling

Sounds like it was intended that way.

It's possible.  The LED on it goes off when it's pushed in.  Which reminds
me, I don't think the ath5k driver allows the LED to blink when it's
transmitting/receiving, it just stays on.
