I'm going to guess it's because the unburnt fuel (and possibly oil) keeps the intake valve cool and clean, but the exhaust valve is hot, hot, hot and cooks the oil as it flows past which causes the cooked oil to build up on/in the exhaust side of the house.

I'm certainly no expert, but I think that the specs that you often see listed for rings are the end gap and clearance in the grooves (between the side of the ring and the edge of the groove that it's in).
