Definitely not the same, at least there in 2 different bins and two different prices.

I'm perplexed!
Calling a specific malt "2-row" just sucks because, like pointed out earlier, all unmalted barley is either 2-row or 6-row. Both of the malts you listed are 2-row.
From those links, it's clear that the "2-row" is much lighter in color (1.7L) than the pale malt (3-4L).
So, their "2-row" is very close to their pilsner malt, which is even lighter.
