"Should I call you Monkey D Al?" is not me saying I don't know your name.
"It's definitely not the same" is just you saying nothing. These two things do the same thing, a character in the show asks if heir the same, it is shown visually in the next chapter -- but they aren't the same?
Here's something else, Jinbei is asking because he calls his COA Kairagi Glaze. We already know haki goes by different names...
Also, we have their vivre cards. They ALL had haki pre TS. The simplest explanation is the best.
