Ohhhh, because its so loud in the stadium, he could
only see her lips move.. - that's a good one.

I don't think that's it, since the goal that everyone remembers was scored in Russia, so Gord must've been "sitting beside you" on a couch somewhere watching it on TV. So if she said she didn't give a fuck about hockey at that point, he would have been able to hear it and not just see it.

I think he's just being colloquial and alliterative: "s.aw s.omeone s.ay" vs. "h.eard s.omeone s.ay".
