how to use two mattes for one object

[S_ A]

Hello,

I wanna hide the moon in two places. I used matte for place 1. but how can I hide it in second place using second matte?

Thank you.

Duplicate the layers, pre-compose them and use the resulting layer in the parent comp.

Put both hiding places on the same layer then use that layer as an inverted alpha track matte.
