It's like a strike zone. Each one is different, and it doesn't matter what the rule book says.
My own LHP son has a boderline-balk PO move that is highly successful. He was called for a balk by an ump in a tournament and I noticed the next PO move he changed it, worrying about balking again. After the game, I said no way, you keep using your "balk" move as long as it works 95% of the time!
TGF having seen your son's move he is not even close to a balk. He goes straight to 1st with room to spare. LHPs are under the same rules as a RHP but it is far easier to throw over. LHPs are at a dissadvantage sinc the runners stay closer to 1st expecting the move.
I understand what you're saying that the runners stay closer to the bag (usually 2 1/2 steps vs. 3 for RHP) but I disagree that this is a "disadvantage" for the LHP. Yes, maybe a disadvantage if referring to the PO move itself, but overall, the whole point is to control the running game and if they're closer to the bag, job accomplished!
BUM Yes but I was talking about PO. If you PO a couple guys during a game they tend to stay even closer. I have always considered 2+ as dead meat if a LHP with a decent move,is on the mound.
Some say it is an advantage for a Lefty, but in some cases, I would beg to differ. Because a lefty has an advantage with the pickoff they tend to use normal leg kicks on almost every pitch. Baserunners tend to go on lefty first movement, thus when they guess right, better jumps and better success. When they guess wrong, pitcher advantage.
