Delay Dead Ball for a Balk in USSSA?

[jeff d]

Digging up this old thread because of something I saw this last weekend at a U-trip Super NIT event and need some help understanding.

Balk was called and batter put the ball in play, but is this the correct way to signal the delayed balk? Isn't it to point at the pitcher and say balk and let the play continue before making the ruling where everyone goes?
For me this ump is calling time...

There was a discussion after by the coaches and I'm still not clear on why this isn't signaled like this. It's gets more confusing because he then puts his hands downs and then points up with his right hand and rolls his wrist like he's signaling a home run without his hand above his head. Is that some live ball signal I don't know?
