You're not following (at least I don't think you are). Graeme sees what I mean.There is a difference between a incorrectly taken restart and an incorrect restart taken (but the restart the referee deemed as correct).
We can use @RustyRef 's goal kick vs corner kick here.
Ref stops for a dropped ball. The ball Is not dropped by the referee to a player from the team who last touched the ball.
That could be reviewed, just as a double touch, or ball not stationary.
As we dont actually know why play was stopped, we do t know the restart But if as Graeme was suggesting, Mike Dean willingly let Fabinho drop the ball to himself, surely that gets looked at.
