Yes.  This is the whole point with --export-secret-subkey.  

Without the secret primary key you can't add a new key, revoke one
etc.  So if your box gets compromised the cracker can "only" use the
subkey to decrypt all messages encrypted to this subkey.

The procedure after such a compromisation or at times when you want
to change certain properties of the key (say, to change the
encryption key to get some forward secrecy), you have to do this
with the main copy of the key which of course should not be stored
on the automated box.
