Can anyone go into more detail about what they're talking about here? I didn't realize IE had a "CSS selector limit." Seems like a funny thing to mention when you're talking about how optimized your site is.

Yes, the magic number is 4095 selectors. And it's still true, even in IE9.

Do they really need that many selectors - it can't be good for performance?
