Strange batting technique, legal?

[RKBUmp]

Just got back from nationals and we had a batter that had everyone scratching their head. UIC was going to try and watch her to see what he thought but they got eliminated before he had a chance to see her.

Lefty slapper, she would take normal stance, but on occasion as the pitch was coming in she would drop her left hand from the bat, take the bat with her right hand and bring the bat around behind her back, grab it with her left hand and then do a running one handed drag bunt. I really wish I had video of it because its hard to describe in exact detail. The first time she did it to me I had to stop and think about what the heck I had just seen.

Initially UIC from our descriptions said he thought there was probably nothing wrong with it. Later he said after thinking about it he may consider the bat being moved across the front of the body as a swing, which would result in any contact with the ball after that being a dead ball. Opinions?
