Not entirely

Before the Collision scenario gained general acceptance, the best model of the Moon's origin was one of capture, slow orbit reduction in a retrograde orbit, and then a critical even where the orbit angle rotated rapidly and flipped to prograde and the Moon began to move away again. This Gerstenkorn event (spelling may be suspect) was well-supported by physics and orbital dynamics.

it happens that we now find 'easier" ways to "do" the Moon, but this scenario is still valid for other Urths, other Muuns...
