Think you're wrong on when he re-signed. From what I've found he resigned June 29th, so the last day eligible before free agency opened up. He signed a 2 year deal that is only guaranteed for $250k in year 2, so basically nothing. It was a $25m over 2 years and he's making $12.65 this season and if he were retained he'd make $13.28 million. Sounds like the $250k is sort of splitting the difference, if the deal didn't have raises and was flat. He's not playing for Washington. I'd guess they didn't know they'd get Jonas Valanciunas so Holmes was insurance while also being trade bait. He's essentially an expiring contract because no one will let a 250k cap hit get in their way.
I can't find any preseason stats or injury information for him. I imagine he's just hanging back and getting paid. We should see him moved eventually.
Info on the extension is in this article.

That matches what BBReference has as well.
I guess he did play in the preseason. Can't find much of any information but he's listed here on a Wizards fan site, like Bright Side, as the leader in preseason PPA. What PPA is, I'm not sure. However he did play so that's some of the puzzle solved.
Now that the preseason is over, let’s break down how the Wizards did statistically
