There's a huge difference between what Surfer did to Bill and what Thor did to Surfer.
Bill and Surfer were already engaged in battle, therefore it was a perfectly viable tactic for Surfer to use the board to attack Bill from behind.
But the fight in the preview between Thor and Surfer, Thor surprise attacks Surfer while he was still talking to Odin from behind.
Starting off a battle by attacking the person from behind his back while he's talking to someone else is way cheaper than using the board in mid battle.
