I'm not sure. I don't think so.

It's still a problem. Instead of conflicting satellite downlinks,
you have ground users preventing other ground users from hearing
the downlinks. AO-10 is quite weak and no doubt FM uplinks in the
same vicinity on 2m would not be appreciated. It really doesn't
fit in 2m. You could use 23cm up though.

In case you haven't noticed, I don't live in either of those places.
