Granted, Fox, both moons must come from somewhere! Most objects do have a tendency to circularize in an equatorial orbit (with lots of time). They do ,however, look very much like the asteroids, though asteroids very a lot among each other (lots of dust, very little dust, potato shaped, 2 fused asteroids, coming from a bigger, broken world, or formed entirely separately from any other body.
What's interesting is that the Moon (ours) is 5° from the equator, not on it.
I'd say that captured worlds have a better chance not to orbit around the planet's equator (like Triton around Neptune or all those small Jupiter moons ending with "e" are in a retrograde orbit, while the small ones ending with "a" are in a inclined orbit (but not retrograde) too.
