I think you are reading something Dan did not wrote in his reply.
I told you how it works. It was possible in some circumstances to delete comment that was paid out, but it was considered a bug and fixed for Hardfork 19 (block 12988978 at 2017-06-20) by steemit devs. When HIVE forked from Steem it inherited that behaviour.
You can't delete comment after cashout, but you can edit out all its content. Of course since blockchain is immutable, it will still be possible to access old content of the comment, but by default it will appear empty.
