My understanding is that buying an NFT is essentially buying the right to control a cell in a spreadsheet (the "shared ledger"). If you buy the NFT, you are buying the right to have your name in the "owner" column of a line in the spreadsheet that corresponds to a particular media identifier, at least until you transfer that right to someone else.
Absent further agreement by the parties, buying the line in the spreadsheet doesn't mean anything. You don't actually own or control anything other than having your name in that cell of the spreadsheet, next to an identifier (e.g. a URL) that identifies a piece of media.
There could be a thousand lines in the spreadsheet tied to the same piece of media. I.e., the original author of a piece of media can sell as many cells in the spreadsheet as he or she wants.
Owning an NFT -- meaning controlling the cell in the spreadsheet -- does not mean that you own the copyright or even that you have a license to display or copy the work unless the copyright holder chooses to tie those rights to whoever is in the cell in the spreadsheet. It just means that you control that cell for the time being.
I haven't seen the terms for this particular NFT sale, but there is no reason that they needed to remove it from YouTube unless they decided they wanted that to be part of the transaction.
