facing a switch pitcher question

[ame=http://www.youtube.com/watch?v=-2oD8KzxS14&feature=related]Switch Hitter VS Switch Pitcher - YouTube[/ame]

how does a switch pitcing rule go.... watch the video it may explain my question more

dont quote me on this but the pitcher cant just switch back and forth. I think he has to stay as one then once he switches he cant go back.


edit:
I was wrong

The pitcher must visually indicate to the umpire, batter and runner(s) which way he will begin pitching to the batter. Engaging the rubber with the glove on a particular hand is considered a definitive commitment to which arm he will throw with. The batter will then choose which side of the plate he will bat from.

The guidelines also permit both the batter and pitcher to change positions (from right-handed to left-handed or vice versa) once per at-bat.

I wonder if this still pertains if the pitcher, for whatever reason, doesn't finish the at bat and a relief pitcher who throws with the other arm relieves him.
