AA clearly defines the definition of "overweight" in the sentence just before yours:
For the destinations identified below, boxes† and excess, overweight (more than 70lbs.), or oversized pieces will not be accepted for transportation.

And the OP does seem to be speaking explicitly of "overweight" (i.e. 70lb+) bags.
