OK,

Addressing the ball = taking a stance + grounding the putter.

DEFINITIONS
A player has "addressed the ball" when he has taken his stance and has also grounded his club


Many of the players were taking their stance, but not grounding the club, therefore, no penalty if the ball moved and they could back off all they wanted.
