Mine definitely work that way. As others have said, it is also 
important that they are interlocked against the doors opening when the 
vehicle is in motion. I built a little logic box using several tiny 
relays and some diodes that performs several functions:
1) disables the door release relays if the doors are locked
2) disables the door release relays if the car isn't in PARK (uses the 
starter disable signal from the auto transmission--could also use the 
parking brake warning light signal)
3) makes one of the two remote buttons open the drivers door and the 
other open *both* doors (for maximal coolness, although the full effect 
does require careful matching of the t-bar adjustments to maintain 
synchronized opening).

So, you have to unlock the doors first (using the standard logic of the 
alarm, and then press one of the "door open" buttons. I have never had 
a problem with unintended release.

If anyone requests it, I can post the schematic of this box.
