That's right, we don't have a way to differentiate between great-circle edges and loxodromes on geography (or vice versa in geometry).
You can approximate a "square" by densifying your east-west lines in the places you want vertices to go, but the inter-vertex edges will still be great circles. You can do that by densifying in geometry land and then casting back to geography. P.
