Hello Xherdan,
The reason for that step in specific is that the feature where the same web dispatcher can forward requests to multiple systems is quite new. This way, even informing any message server at that step, as soon as you add parameters like "wdisp/system_X" at the profile, the parameters "mshost" and "msport" will be ignored.
Nevertheless is still good to comment them.
Cheers,
Ian Segóbio.
