When vertical…yes it keeps your bike upright. When you initiate the “counter steer” by pushing on the handle bar the result kicks off the “precession effect”. Which means the gyro (your tire) basically wants to fight back against the force…the more you push it ..the more it fights back. Helping the bike to lean. Then the traction and centrifugal force comes into play to help keep you from laying it down. Same effect if you want to “pop” upright outta lean to go back straight in a hurry.
