Exactly; there are rather perverse incentives at work. Without a meaningful incentives program, employees are only going to try to do well enough to not get fired. If they work their asses off selling consoles, they make minimum wage. If they're surly, lazy, and generally unhelpful, they make minimum wage and they don't have to do as much.
From a "what's good for the consumer" standpoint, I could see a clerk trying to convince someone who seems to want a PS3, but who doesn't know much about it, to buy a 360. It's simple fact that it's a more popular console in the US market, and size of the difference between the two means that it's almost certainly more popular among former PS2 casuals. It's apparently the case that knowledgeable casuals tend to opt for the 360, so it's entirely justifiable to try to convince ignorant casuals to go the same way.
