I've never heard of a BT speaker phone that holds contacts, so I can't speculate intelligently there. Usually the contacts are held in the phone.

BT devices can generally only hold one connection at a time, so your phone (for example) would not be able to handle two connections at a time - one on a call and one to an eavesdropper. However, if you were NOT on BT, then it depends on the phone -- does it permit more than one connection to the mic at the same time?
If they were able to monitor a call, then the encryption would indeed be a moot point.

Notwithstanding what I said above, only when you are talking to a passenger. You can also talk THROUGH the BT - so picture you're driving along and someone comes over your BT headset/car kit saying, "Dude.. Those shades don't match your shirt..."...
