If I saw the same lat/long video as you, the young woman had a "mind blown" episode as the thought of an "accidental coordinate swap" sunk in. But it's completely silly, for two reasons.

A point in Antarctica, or its ice shelf, requires a latitude between roughly -70 to -90 degrees south. With coordinates swapped this corresponds to a longitude between -70 and -90 W. Take a look at a map of North America. The band encompassed the entirety of the U.S. East coast, much of the Midwest, as well as Toronto and Montreal. That slice covers a huge land area with a large population. Any point within it, coordinates reversed, puts you into Antarctica.

The idea that advanced alien creatures with space portal and/or inter-dimensional technology (whatever that might be I don't know) are navigating from who knows where using - if you can believe it - a human invented coordinate system? That makes zero sense.
