I think you can prove/disprove this quite easily.

Pull a driving range mat over to the chipping green, and hit a few shots.

OR

Make several markings on a ball and borrow a highspeed camera to check the rpm's.

This might be one of those things that don't make sence, but are actually true. This kinda reminds me about dropping items with different weights, and realizing that they will hit the ground at the same time regardless. If you don't belive me, try it. If you drop a 1000kg ball, and a 1kg ball, they will hit the gound at the same time. This is true for any weight, as long as air, or shape doenst interfere. (for instance, you can't drop a feather, and a ball. You can drop a ball thats the same weight as the feather though, and it will work.)
