Can't address the MN situation, but you are right that:
1) It's not a DD
2) It often is called that way.
I did see it happen in an NCAA game and the official shook his head "no" and gave the "Fumble" mechanic (think football -- juggling the ball while going out of bounds on a near-catch).
The crowd yelled, the coach came up, the ref signalled, the coach sat down, the fans still yelled.
I"ll try to add this to my mechanics list.
