I am not saying “they’re going for the disc so it’s not a foul”. I’m just saying that if we follow the written rules and definitions, I can’t see how contact after the outcome of the play can be considered a receiving foul, unless it’s dangerous or significant (which I guess are sort of the same thing, no? How would you define ‘significant’ in that context?).
12.9 says all players must avoid contact, but that is not to say that if there is contact then it is automatically a foul. It’s in the rules that some contact is not a foul.
