"Lets do this, yes it was high hitched , if thats what it will take, but in the classic sense , no it was not high hitched, but lets use that . My point was there was no gap ."
Lets assume for argument that we have 4 extra slip discs. That will not allow the subject hitch or any hitch to latch. There will still not be a gap. I would call that a high hitch even though the pin is not on top of the jaws.
But in this case the OP did not close the hitch plain and simple.
It would not matter what hitch is used including the B&W it would result in a dropped trailer. Now it will be said that that can not happen with a B&W as the arm would be open. But if you look at this picture it is clear the subject arm was also in the locked open position.

In this picture I believe you can see the pin just to the left of the jaw. You should not be able to see the pin when the hitch is closed and latched.

There was nothing wrong with the hitch is was an operator error.
