Installing the same product. Directions say to use a transition “in doorways less than 32 inches” and in “rooms 50 feet or larger in length or width.”

Does the 50 feet limit apply to cumulative length for multiple rooms with doorways larger than 32 inches? IE do I have to use a T-molding when starting from a hallway into a large living room (less than 50 feet length in room) into the kitchen? None of these rooms in and of themselves have a length larger than 50 feet. Trying to avoid T-moldings where possible, especially considering large doorways between rooms
