Contact on an iron off the ground is almost always made with the ball contact the face BELOW the center of gravity, so the face kicks DE-lofted, and this increases spin as well.

I get it, but how do you explain that when you top the ball (assume same angle of attack) it decreases spin even though the ball is well below COG?

Friction will play a role also like Mike said
Like when you hit a flyer, it launches higher than normal contact from a fairway type of lie

Because there are two totally independent factors -- where the ball is being struck on the clubface and where the clubhead struck the ball.
If the ball is being struck above its CoG it does not matter what strucks it, even clubhead sweetspot (of course, hypothetically, since it is practically impossible to hit the ball above its CoG with a middle of the face but rather by bottom of it).
Simple physics of collision of two objects rules.
