The arms cannot be completely passive or work down during the downswing.
Those feels may temporarily fix a beginner or a massively over the top slicer, but it’s the equivalent of telling a golfer who aims too far right to just feel like he’s aiming too far left.
To over-simplify, the OTT slicer has his hands and arms working out and away from the target and the correct move is out and toward the target.

Depth in the backswing=horizontal distance from the ball in a 2D down the line video.
Backswing also contributes. Not enough depth with the hands (butt of the club), vertical shaft and/or OTT is hard to avoid. Early depth (whipping it inside, low and slow) and late lift, vertical shaft and OTT is hard to avoid.
Late depth, arms and hands out and forward to start the downswing.
