I always mount my pumps there. I was cleaning the dirt and dust out of pumps too often when mounted on the downtube. Some of my riding is on gravel trails, and in late summer if it has not rained for a while it is really dusty. Less dust on the seat tube mounting.
But on a tour, if I am in an area where I am concerned about theft (maybe 10 percent of the time), the pump is in a pannier. Thus, when I go in a grocery store in an urban area, the pump is not sitting out there waiting for someone to say, that looks nice.
A friend of mine mounts the Lezyne upside down, he said it won't accumulate water in the rain that way. But I do not recall that being a problem for me, so I do not do that.
