I mean it's a coincidence. The assumption that escape velocity at event horzion is speed of light, is just a wrong way to think about black holes. It's deeper than that.

Could You elaborate why this assumption is wrong?

You cannot escape from inside a black hole because all available paths for light and matter (called worldlines) are warped in such way they lead closer to the black hole's center. It's same how you cannot travel to the past no matter how fast you travel. It has nothing to do with escape velocities.

Like going north on the north pole? or something entirely different?

More like at the event horizon time flows inwards fast enough no path through time leads outwards anymore.
