Mmmm. There must be some epic level shenanigans going on somewhere to make that kind of tax liability recording even possible.
A stock can only have a single holder of record, and only one dividend payment should ever be made to whoever the holder of the stock was at the time of the payment.

If that article is to be believed, I'd suspect there was a bank who needs some serious auditing; because there is simply no way there should be any ambiguity as to who the stockholder of record is at that time; and the issuance of a multitude of "tax certificates" to multiple individuals implies they fundamentally mishandled that particular taxation event.
Transactions are atomic, and serial in nature as far as finances go. Automated or manual. They must resolve down to chronological order.
This is also part of the reason the Feds hate structuring, and will stamp it out in any form they can get enough information about in order to recognize it. Don't be like these people ever.
There is no moral or fiscal imperative to commit or concoct structures/mechanisms capable of becoming or facilitating tax fraud. Hell, this exact kind of chicanery is why AML/KYC/tax law ends up making normal financial service providing such a slog; because every link in the chain is yet another gear in the machine. If it seems like you're having to go through lot of hoops to do a relatively straightforward transfer of value, odds are, you may be taking part in some form of either structuring or other financial engineering. If you think that's a tenable of affairs, have fun, but when it comes back around, don't be surprised if there isn't much sympathy to be found.
