So the question is not how many steps, the question is when is there control of the ball. The rule is written differently for a loose ball compared to a dribble (which does require 2 hands on the ball) Because there is a difference that implies that two hands are not required for control of a loose ball. But i'm not a referee. I'm just someone that argues with IRS appeals officers about the the meaning of written tax law, regulations, and treaties.
