Multi DB Configuration Question

I'm installing Multi DB on our system and I have a question about the documentation.

In the final section about editing the move-blogs.php file the documentation gets down to editing lines 21 - 29. In looking at the move-blogs.php file line 23-26 contains the information for the conneciton to the databases. Line 24 is $dbhost = 'localhost'. the documentation did not mention to change any information here but my db server is NOT localhost - it is a remote host which I did correctly specify in the db-config.php file.

Should line 24 still be left as 'localhost' or updated to reflect the correct IP of the remote host with the databases??
