No no, it's the same.

The OFAC apply to US companies only and forbid VISA/MasterCard to manage her transactions (and a LOT of others companies ... like a lot, not just Visa and MasterCard).

Legally Europeans bank shouldn't apply US sanctions, maybe they do, but legally, they should not (CJUE thing, I'm not an expert). I don't think it ever happen, because ... money launder generally doesn't complains about US sanction, it's wasn't a problem.
