I believe the 2009 Yahoo-Bing agreement is still in force, where Bing provides search results on Yahoo.com:

I know the search I performed now on Yahoo states "Powered by Bing™" at the bottom.

Yeah, I thought that could be it as well but was at the bottom of the Yahoo result:

Given they are identical results it's pretty clear it must be a shared index I suppose, that or the leaked memory was cached.

Yahoo provides a front end to the search results, Bing provides the crawl/search/archives.

What the hell does Yahoo even do anymore? Just email? Or is that just a proxy to hotmail?

Finance, News, Mail, Fantasy Sports, etc to name a few where they are still in the top three of the category.

Yahoo was never really a search company (even its founding, it was a "directory", not a "search"). Sure, they pretended fairly well from 2004ish (following their move off Google results) to 2009 (when they did the Bing deal), but the company never really nailed search or more importantly search monetization despite acquiring one of the first great search engines (Altavista) and the actual inventor of the tech Google stole for its cash cow Adwords (Overture).
