The AC compressor shuts off when your engine exceeds ~4k rpm on most cars anyways. It can only spin so fast without causing problems. And if you’re trying to pass you’re probably exceeding 4k (on a gas engine) and the car is smart enough to figure it out.
A lot of newer cars don’t have the clutch anymore, they instead use a pressure valve to reduce pressure on the compressor. Should have the same effect though

But it gives you a fraction of an edge on the beginning before you hit 4k in that scenario. So you have a faster start.
