“The simple answer…” But that isnt what Rav Acha said. Rav Acha said that he had no hirhurim whatsoever from it. Or put another way she didnt make a roshem it was like holding a beam, he didnt notice her
If I understand your correctly NOT having a yetzer haraah, ie viewing a kallah as a beam is LOWER than havign a yetzer harah. It means less kedusha. Im’ asking on his “beam” response not on his action. If he said “I have a huge yetzer hara for her – bigger than yours! but bmkom mitzvah its muttar” or somehting like that , I’d hear. but that wasnt his reply.
