I don't get it. Castling either way would have been better. The king hinders white's major piece coordination for the rest of the game.

The battery pressures the long diaganol; The plan now is to attack on the h-file, with a timely bishop sac at g4 likely.

The point of the knight's journey is to keep black cramped. The bishop at c8 seemingly has nowhere to go, and the bishop blocks the rook out of the game.
