Good point, but you're still arguing only one side of the story.

You said that letting off the throttle allows the suspension to decompress which makes the bike run wide.... but done smoothly, it can decompress the REAR more than the front as the weight transitions forward. This reduces rake and trail, makes the bike inherently less stable, thus more maneuverable and you can lean the bike easier as long as you keep your arms loose and don't transmit all that force onto the front end.

Turning radius is a function of lean angle and speed... reduce speed and as long as you can maintain chassis stability & lean angle, you're reducing the arc of the turn.

So again... it can have EITHER effect. It all depends on whether or not your inputs destabilize the bike & make it stand up & go wide.
