That's because in the 4th quarter, with ~11 minutes remaining, Saha swapped out of the PG spot for less than a minute. Then he went back to the PG spot, so he ended up with just 47 training minutes.
This happens sometimes in garbage time, which started in your game with 1 min 35 sec remaining in the 3rd quarter. Poulakis was at the free throw line, and your coach wanted to make a substitution for him. But since he was at the line, the coach couldn't. So instead, the coach put Saha there. It's been known to happen some times, just one of the oddities of how the substitutions work.
BUt really, 47 minutes isn't that much of a decrement in training efficiency I think.
