The link to this BBO Movie is Both Kings are Wrong

This is a one hand Movie, presented double dummy. The author misplayed it at the table, and shows us his misplay, and then show the winning line, that works despite both kings being offside. The Movie has no quizses, no voice track, and should take only a few minutes to watch. The auction is one you don't see everyday, dealer opened 2NT, and then over a 4♦ transfer, made a super-accept of 5♥. I don't ever remember seeing such a superaccept before, since partner could invite slam by bidding 3♦ and then raising 3♥ to 4♥ (mild slam try). The super accept or texas transfer seems counter to normal bridge and risk playing too high in five hearts.

Slight issue; One of the kings is onside.

Yeah - I'm not sure the winning line is a correct line. If E takes the J with the K, you only* make when diamonds are 3-3, where "straight" finessing wins if the K or T are doubleton.
If W has the ♦K and ducks, probably you follow up with ace and another, again making if diamonds are 3-3, if you catch a doubleton king (and a sleeping W) or a doubleton T. So, it seems starting with either diamond finesse is equally viable, percentage wise - both make on diamonds 3-3 and if the K or T are doubleton and the K is conveniently placed.
As for the club finesse, that's a practice finesse, so it shouldn't be part of any line.
I think maybe the best line is to draw trumps ending in dummy, cash ♠K pitching a club and then losing a diamond trick to W, hoping to endplay him into giving you three diamond tricks or the ♣Q.

* Caveat: I don't know squeezes
