With the disconnect active - with no magazine in the gun - it keeps the trigger bar and sear apart. When a magazine is inserted, the bit of metal that blocks them moves out of the way as a result of the magazine moving it. The trigger just isn't part of this mechanism at all, except in the sense that the mag disconnect keeps the trigger bar away from the sear.
No effect on the trigger action....
This is NOT the case in 1911's with the Colt-style firing pin block, nor is it related to the drop safety in the M&P slide that's actuated by the trigger bar.
(1911's with Swartz safety mechanisms are a tad different. The grip safety moves a pin into the slide to move the trigger block out of the way. This DOES NOT affect the trigger pull at all. The Colt block adds a smidge to the trigger weight, but if everything is working OK, most shooters would never notice, and few are capable of measuring the change either.)
My old M39 has a mag disconnect - very easy to remove/fix/clean. I'm not sure whether it has any effect on the trigger. I've had it set up both ways over the years (bought it before 1975), but don't remember any difference.
That video, btw, is excellent.
