It took me a moment to figure that out, so here's what's going on there. "It is" isn't the only thing that "It's" means. In past tense you use either "it's" or "it was". So yes and no to what she is saying. In past tense you use the past tense version of "to be". I almost never see someone use "it's" for "it was." Normally you just don't use a contraction there, because it sounds extremely weird.
