No it doesn't make it clear, because it's written by a third party reading the same internally-inconsistent page I am; any information added beyond the Google documentation page is conjecture.

"Gmail will no longer support checking emails from third-party accounts through POP." seems quite clear.

Good god Google can't be bothered to not wreck shit that doesn't cost them much, eh?

Doesn't surprise me too much though, Gmail hasn't seen much maintenance and polish over the last few years.

Personally I’m happy about it. It’s the kick in the butt I needed to get my last remaining crap off Google and shut down my accounts for good.

What does "from a third-party account" mean?

I have a test suite that accesses a gmail account through POP. It's a regular gmail account. Will that be affected?

Edit: Okay I think not. But man is this confusing over whether it's Gmail that's doing the fetching over POP (a feature I had no idea existed) or somehting they're calling a third-party account fetching Gmail emails over POP.
