Correct.
The cause of the hammer dropping is not as simple as it seems. The trigger in a 1911 type is loose in the frame, free to move except for pressure from its spring and the grip safety. When the slide is let drop with the gun gripped normally and the finger off the trigger, it slams into the slide stop pin and jars the whole gun forward. But the trigger, thanks to Mr. Newton, tends to just sort of sit there, so in relation to the frame, it seems to move back. If the sear notch is too "fine" and the trigger spring too light, the trigger will, in effect, pull itself and drop the hammer onto the half cock notch or shelf.
This will not/should not happen with a four pound pull, but some people are not happy with that, and claim to get hernias and all sorts of ailments if the pull is that heavy. So the gunsmiths, professional and amateur, try to satisfy these dear delicate creatures, make pulls that go off if touched by a feather, and then caution the owners that the 1911 is very fragile and not to do anything to disturb it (like actually shooting it!).
That GC trigger is designed to provide a minimal safe pull without bad side effects.
