Do stop thrusts end movement?

[hal]

Gotta wonder...

If a character is knocked back, if the moving character pays the cost in movement allowance, for moving backwards. The example above brings to mind the following murphy's rules mind image:

"Like a wind up toy, an attacker knocked back slides frictionlessly back exactly 36 inches, and regains full traction to finish its movement before it runs out of it's turns wound up movement. At the start of the attacker's next turn, he is wound up again so he move his full allowance"

Frankly, in my games, being forced back with a knock back while moving forwards results in a backward movement cost plus forward movement costs to resume forward movement. After seeing this thread, I'm likely going to require a SECOND DX saving roll at double encumbrance penalty to resume forward motion in the same turn. You can't easily go forward, backwards, and forwards in the span of under a second without some serious potential balance issues.
