Good question

The implication is that whoever set up the interface between the live game feed and the engine didn't do it in such a way as to remind the engine that castling wasn't legal. If set up that way, it rather discredits any assessments the engine might display on the Berlin ending and other similar positions.

There's precedent though. Golombek is reported to have recommended castling in a position arising from a Fried Liver or similar.

Perhaps the current position was fed to the computer every move rather than it following along with the game? It still doesn't make a lot of sense, since presumably you'd give the position in FEN, which includes castling rights. But in general I'm guessing that it went through some intermediate step that discarded the castling situation.
