If you keep reading, the document later details that DPR contacted this "redandwhite" person, who he contracted to kill the other person, regarding false identifications. That seems to add some doubt to your hypothesis, or at least complicates things.

He may have also lied about having paid for a ht previously for $80k to bolster his bluff.

EDIT: Or he was watching too much breaking bad and beginning to assume Heisenberg's characteristics after feeling invincible for earning $80MM

It appears to fit with his persona of being a ruthless pirate, and the language also fits the big talk idea. He was paying for the problem to disappear, and he knew that, but he talked it up for fun.

However, he went too far into his fantasy, and not too smartly, and he'll pay for it.
