Right, because here you have configured a shared namespace for
~/Maildir. If you want to access also ~/Maildir2, you'd need to create a
second shared namespace for it. Perhaps in future there could be some
kind of automated detection of namespaces and putting them all under a
single shared namespace. Configuration could probably be something like:

namespace others {
  type = shared
  separator = .
  prefix = INBOX.shared.%%u.
  location = shared:INBOX.:INDEX=~/Maildir/shared/%%u
}

The above would then map "INBOX.shared.%%u." namespace to other user's
"INBOX." namespace and also export any other private namespaces under
it.
