Is this intended to work for keeping the 2007 UI?

I have a need to retain the 2007 UI for a while on an upgraded farm, and am looking for a way to create new subwebs that have the 2007 UI. I can do it with PowerShell, but thought that this would be easier for administrators. But when I tried to use this to toggle a newly created subweb with the 2010 UI back to 2007, It instead toggled the whole site collection from 2007 to the 2010 UI. Is this a bug or expected behavior, and I'm just trying to use it in a way that wasn't intended?
