Does the BT detection work the same way that WiFi access point scanning works? I know that app developers use this WiFi tech from a client (device) side to determine location, but I am a bit disturbed about the aspect of this being so accurate with BT devices.

Yes passive signal detection behaves like this. Apple uses passive and active Bluetooth in their stores to determine what products you are looking at.
