^You're only correct in one of those three (the height).
Width changes as you go higher due to the chamfering, so that at the rooftop, the tower is some 25% (someone correct me if I'm wrong) less wide.
Profile will only be the same from certain angles. Again, it's because of the chamfering.
Another similarity that hasn't been mentioned yet is a (very subtle) pinstripe glass facade.
It's subtle, but I think I've really changed my view on Freedom since the other towers were unveiled: it would be good if Childs added a few touches to break up the monolith-ness of it.
