Exactly. It has outriggers, and doesn't roll. It rotates.

Yes, but this isn't usually a problem in pianos. It's not the bridge's job 
to control torque effects on it's ends, it's the soundboard assemblies job 
to provide a platform under the bridge that supports it, and the designer's 
job to make an attempt to insure that it does. There isn't anything in a 
bridge/string system to torque the bridge. Bridge torque comes from off 
center load support, and/or soundboard failure and deformation.
