It could be like you said, but poor choice of word if that is the case.
But are you even able to see that someone had a seizure from looking at an EEG after it happened? I was under the impression that it sort of have to be happening while you're measuring.
I've been through multiple rounds of both MRI and EEG, mostly to be able to rule out things like brain damage as a precaution. I'm a little fuzzy on the details as this was done so long ago.
You're correct. Routine EEG (~30 minutes) can capture active seizures and sometimes patterns that might lead you to think someone is predisposed for a seizure. Often patients need long-term monitoring ("LTM") where they are connected to an EEG for several days to tease out the source of their problems.
