It's about friggin time

Bob, a one-handed bowler can shoot spares two-handed so long as his right hand is the dominant hand.
I had to e-mail USBC last season and check when a dispute was made.

Just to clarify a bit more - that is providing he is bowling one-handed with the right hand. If he is bowling left handed with one hand, then the two-handed must have the left hand dominant in order to be considered to "finish the game using the hand you started with."

Correct. Whichever hand the average was established with is considered the dominant hand and must be so for both deliveries. How it's delivered they don't care as long as the dominant hand is the same.
