I think what he wants to say is:
Of course the crafter doesn't lose anything. But as a 60 omnicrafter I can confirm that it really doesn't sit well with me when attempt after attempt for somebody else fails, even if I, personally, don't lose anything. The other one does, and it's a crappy feeling to feel responsible for it even if it's not your fault, but rng's. That's what Culfinrandir was talking about.
