if you accelerated in the direction of the orbit , my understanding is
you would just turn a cicular orbit into an elliptical orbit. ie you
would go out further from the atmosphere on the other side of the
orbit and come back to the original ht where you first accelerated.
this would not result in the shuttle descending at all.

As long as we are picking nits...

You pass through the point (and at the same velocity and direction) where
you LAST accelerated (assuming something else doesn't get in the way)
