Kind of. It is basically a simple indication to any outside personnel that the slide is armed, and opening the door will inflate the slide. Some aircraft have a different arming system which will only set off the slide if the door is opened from the inside, but it will still be up to the ground crews to understand which aircraft are safe to open from the outside.

The 'cross check' that is called for is for the flight attendants to check both service doors in their area and ensure the slides are armed, and is indicating as such to anyone outside the aircraft.

EDIT: dammit thumper. Way better explanation too.
