No, not an embarrassing faux pas, but maybe a little confusing depending on the wording. I'd just edit the comment a tiny bit to remove any reference that the story's for you. (But I thank authors of stories I love in exchanges for writing them all the time, especially if it could have been written for me and/or was really fantastic.)

It's probably for you, at any rate, and they forgot your name. Seems wild, but it happens.
