I had not considered that, Wildhorn. Reading over things though, that does make the most sense to me too. By the letter of the rules and the card text, the target does only change for steps 3 and 4 of combat, which would prevent any other reverse attacks from occurring. This would also prevent any other defenses from occurring as well though. Since the original attacker doesn't become the defender until after step 2 he would not get any chances to avoid the attack.
This makes perfect sense to me from a literal reading, but I'm not certain it was intended this way. Again, since we have an official ruling on it from an Arcane Wonders employee, we should abide that ruling unless it is officially changed. However I will be researching this a little more myself because it does seem a bit odd.
