Continuity mistake: At the end when Flynn is asking Sam to go, Quorra has Flynn's disc on her back. In the next shot she says "Sam, it's what he wants" and the disc is no longer on her back. And then in the next shot it's on her back again before she gives it to him.

More questions & answers from TRON: Legacy
Chosen answer: He doesn't know Clu is dead. And a little prudence never hurts. Flynn knows Clu and clearly it was entirely possible that Clu was still alive. If they all got back to the portal, it made no difference. If Clu showed up to stop them, Flynn knew what he had to do and needed to make sure that Sam had his disc to get out.
