kisshomaru on "[Plugin: WordPress MU Domain Mapping] Does the plugin work if the multisite is installed in a folder"

This is a perfectly valid wordpress multisite installation since 3.5 (I see the plugin says it is compatible up to 4.0). See this:
http://codex.wordpress.org/Giving_WordPress_Its_Own_Directory
So, it is not really a sub-folder, the entire wp is in its own folder under /root/wordpress/. The domain is going directly to http://www.example.com but everything is redirected to root/wordpress/ as per the link above.
I am using subdomain mode normally with all subsites (NOT both sd and sf). It is now that I need to map a different domain to the xxx.example.com when I came across this issue.
Would this plugin work with this perfectly valid multisite installation?
