I think my stumbling block was that I read ἐάν as εἰ + ἄν and I thought it was a conditional clause, and not only as ἄν as you suggest mwh.
I see now that my "Classical Greek Grammar" §50.3 describes that ὄς and ὅστις is interchangeable and even when the meaning is indefinite, there might appear a definite relative pronoun.
