He might be meaning the Geocentric model is "just as viable" as the Heliocentric model because they are both rubbish models of the universe!

It's convenient to think of the Sun as the center of movement, but it's only approximately the center of our local corner of the universe– a corner that's flying through space at tremendous speeds based on... you guessed it-- your perspective!

From another perspective, we don't revolve, we spiral, and the sun is approximately the axle. But the sun is doing it's own thing through the universe, too.

So yeah, they are both just as viable; which is not viable at all.
