You could do
SSH_AUTH_SOCK= ssh hostAAdmin

You would be effectively disabling the ssh agent (by emptying the
SSH_AUTH_SOCK env var to the child ssh process),
which means that you will need to enter the password manually. Still,
seems better than the current approach.

A more advanced approach would be to have two ssh agents on different
sockets, and switch among them, playing or
perhaps with wrappers, or having SSH_AUTH_SOCK point to a symlink that
you repoint to one or another as you change
hats.

I know it doesn't solve the underlying problem (yes, it looks like a
bug), but hopefully it can make your life a bit easier.
