I would say the 3 tire lever tire/rim combo is the exception, not the rule. I have mounted countless tires (generally around 5 a day) for 12 years, and within that time have only seen 2 tires that you needed more than one lever to mount/remove.
Anyway, that said, it is remotely possible (in that anything, to some degree is remotely possible) that the rim is so far out of spec that tire could just roll off. But for this to happen, it would have to be SO far out of spec that when you inflated it, it would be very hard to keep the tire on the rim, without a tube coming out between the rim and the tire.
I would agree with 'tunnelrat' and guess that it was a incorrectly mounted tire, and that the wheel itself, in this case, is probably not at fault.
