Go back to school.
I think the point is that the pixels themselves aren't square - those 200 lines fill a 4:3 TV set... Or at least that's my understanding, which could be utterly wrong.

So quoting pixel metrics for non-square pixels is irrelevant in this case. (I think that's the point that was being made, but as said I could be wrong!)
