Question about loot etiquette

[Beckett]

It feels really dickish, and I was struggling to figure out exactly why. I thought about it and realized there's really not much difference between him rolling to sell an orchestrion roll and everyone else rolling for gear. Either way, your group is going to run the raids until everyone gets their drop.

Breaking it down, I feel like the difference between the rest of the people joining this group and the guy rolling to sell the orchestrion roll is

"Let's help each other out."
vs
"I'll help you out, but only if I get paid."

In both cases, all parties are getting something out of it, but one just comes off as a lot more sleazy.

Spoilers: There isn't.

"I'll help you out, but only if I get paid."

The only case in which this doesn't apply is if someone had already gotten their drop and goes in there again, but this was obviously not the case as their friend managed to roll on loot. Even OP only helped their party clear because they wanted the drop at the end.

In what possible way is it like the second example if the guy has no guarantee he'll get the drop he needs? He's joining the party to take his chances to roll for the drop he needs, EXACTLY like everyone else. There is literally no distinction except the one people make up retroactively because they got butthurt.
