You're supposed to lean the bike toward the foot you're putting down. Leaning it the other way would be very awkward and a little dangerous. You might not be aware of it, but the way you get off a bike is by initiating a slight lean first, then putting your foot down as the side of the bike gets closer to the ground.

Chain lube is pretty much normal. But if you're getting it much more from one bike than you are from the other, my guess is it's the difference in the lean angle when you dismount. Which you can control somewhat, but you don't want to be putting your foot down too far away from your center of gravity, either.
