Kind of. Tsukishima can alter the past, not just memories. Do you remember his fight with Byakuya? He could cut the ground snd alter its history so that he planted traps there "long ago". In this instance, he created a past in which Yhwach did not break Tensa Zangetsu. Orihime couldn't fix Tensa Zangetsu because Yhwach broke it in the future, so pretty much all futures lead to Tensa Zangetsu breaking, hence her not being able to fix it. But with Tsukishima's new past, as he said, she should be able to fix it~
