Pretty sure that's how it works with a lot of vehicles. It's the least expensive but most consistent way to do a security system, since it doesn't have to deal with tempermental and false-alert sensors like audio broken-glass sensors, pressure sensors, radar, etc. The only thing it protects against is having the doors opened.
Case 1: Burgler breaks your window, opens door to get into car. Alarm would go off the second they opened the door without unlocking it from the remote.
Case 2: Burgler breaks the window, climbs through the window, takes a bunch of stuff and leaves, without opening the door. No alarm.
Case 3: Burgler tried to be quiet and use a slimjim or window wedge, coathanger, lock smashing, etc. Alarm will still go off once that door opens.
Case 4: You lock the door with the button on the door or with the normal key (not the remote part). Alarm is NOT armed, so nothing will happen. Badness.
Case 5: You leave the windows/sunroof open, but hit the lock button on the remote. While you're not protected from somebody leaning in and taking things, or even climbing through the window, you are safe from people who would reach in and open the door from the inside, because that will trigger the alarm.
Basically, what you want to do is get in the habit of only locking/unlocking with the remote, never with the normal key. Anytime you arm the alarm with the remote, but don't also disarm it with the remote before opening the door, you'll get an alarm.
