Check swing

[Del-Blue]

While I was looking through the Fed case book to find sonething on the umpire asking the batter is she is the correct one,Which by the way I couldn't find, I came accross this.

Check swing:
10.1.4 Situation B1 attempting to check her swing,carries the barrel of the bat past her body. The umpire calls this a strike.
Ruling:
The umpire may note whether or not the batter's movement carried the barrel of the bat past the batter's body, but,
This is what got me thinking???

The umpire's final decision is based on whether or not the batter ACTUALLY STRUCK AT THE BALL.
Now, If I think she actually wanted to stop her swing, but the bat went past her body, would I or could I not call a strike??
