It was September and he did it from a spread eagle:
Michelle's Instagram post appears to reference a previous occasion when she skated with Evan and Vera. Though Michelle posted this throwback photo in September 2019, these three did not go skating together in September 2019.
Last September, Evan was surely somewhere with Dang planning their December 2019 wedding.
ITA this is a lovely article reflecting back on Lysacek's career which culminated in his 2010 Olympics gold medal victory. Phil Hersh has gotten better at writing about figure skating since his retirement. I can't help but think he took heed of some advice given to him on FSU a few years ago.

Perhaps also, not having to write under deadline, has given Phil more time to reflect.
It's interesting that Johnny Weir isn't at least mentioned in passing in the article. I recognize that Evan's and Johnny's accomplishments stand alone, and it isn't crucial for either to be mentioned in a write-up about their separate careers. However, with the mention of other rivals, even Jeremy Abbott in passing, and of course Plushenko (who is cited more extensively in connection with the 2010 Olympics), I think that Johnny not being mentioned is a bit of an omission.
Early in their careers as juniors and as seniors domestically, Johnny & Evan experienced a direct, yet respectful rivalry. I think it was an important rivalry in particular for Evan. This, in the sense of Evan realizing he had to push himself even harder to compete against a skater like Johnny who was so naturally gifted. Whereas Johnny seemed in some respects to take his talent for granted, Evan never took his skating for granted. Evan had to work extremely hard and then some to reach the pinnacle of his career.
Along the way, Evan and Johnny had some crucial match-ups on the ice. It was sad that the media and U.S. figure skating propelled their respectful rivalry into something that it wasn't, which IMO in some ways detrimentally impacted the U.S. men's discipline. The good thing is that the real, underlying generous-spirited impact of the Evan/Johnny rivalry, heavily influenced the friendly sportsmanship the U.S. men's discipline has epitomized ever since those not-too-distant days of 'wine and roses.' Or more aptly, days of 'grind and bruises, and of hard-won victories.'
