Good question!!

However, after Black moves 1....F3-G4, White wins with 2.D5-C4!  Now, if 2......G4-F3, then 3.E4-D3.  Next, if 3....F3-E2, then 4.C4-B3! E2xC4, 5.B3xD5 wins.  (Other retreating Black second moves allow White to defend his Castle with one piece while advancing toward Black's Castle with the other piece, as might have happened in the game.)

By the way, I think that if any Cam position is drawn, it will probably entail an ending with two pieces vs. two pieces.  That is the most common type of drawn ending in Camelot, though I probably shouldn't say "common" since with accurate play, almost all Camelot endgame positions are not drawn.
