I am afraid I do not understand this particular point.
Jason ends Schindler's List in a crouch on the ice. He ends "Melancholy" (at least this version) staring up at the sky. Now, both are "sad" endings I guess, but they are different positions. I also highly doubt Rohene is looking to David Wilson for choreo, but you never know
If anything, I thought Andrew T.'s ending pose, in a crouch on the ice, was too reminiscent of Jason's Schindlers.
I think Skatesocs means that Jason used the spiral sequence from Schindler's List for the ending. And yes the element itself is the same-- as in he does the spiral and the knee slide. But I think it worked with the music. YMMV. I mean Starr Andrews specifically picked Jason's spiral as the standout moment she would love to have -- so I don't begrudge Jason for using the spiral here.
Honestly, I think it's an ask for skaters to choreograph separate programs. And yeah I just don't think there was a lot of time even if you wanted to. In Jason's case, -- I think Chicago area rinks opened in early June and Jason was trying to get into Canada during parts of that month, so at best he probably got 2-3 weeks of ice time in the U.S. and then a few days at TCC after he got out of his 14-day quarantine.
ETA: I really loved Jason's SP and hope it's THE SP for whatever season we have in 2020-2021. I really enjoyed everyone and I think the top five were pretty strong, though I think my top three would have been Jason, Tomoki and Emmanuel.
