Seems intentional to me, but I'm not there and had no game flow context. Judging intent though and order...
First occurrence: BR bases loaded, high and out pitch, batter backing up and gets hit... No way she's throwing that ball to a fielder... In fact she looks to stare down the batter, then start talking to the PU pointing at the batter as if she got in the way. Could she claim the ball "slipped" from her hand, perhaps, but based on the point I think not. At this point my radar is way up.
Second occurrence: BR "shows" bunt w/ R2, in 10-5 game, 0-1 count, B6, 1 out, R2 is not going towards 3rd (just what seems to be the normal extended lead), F5 & F6 are not going towards bag... Looks pretty bad because batter backs up and gets hit.. No way she's throwing that ball to a fielder. That's a message.
Once is ooops (barely) perhaps w/ warning, second time it happens, then it's a pattern and trying to send a message. If a P did that (intentionally throw at batter) - you are required to eject. One has to think the other team was coached to know this team/C has done this before. I say this because in the first video you can see the 3B coach walking towards the batter to instruct something, then walking back. That coach didn't even think to ask the umpire about intent. In both videos the 1B coach does nothing - it's as if it's expected. I see no BI in either case especially since there's no actual play being made for which the batter is hindering.
