In Snow Leopard, the listing of Preferred Networks (for the AirPort) was bound to the Location. In other words, each Location would have its own set of preferred WiFi networks. This was actually useful for someone like myself that moves around a lot between a dozen known locations with known wireless networks. I could set my preferred list based on the location and change networks easily simply by changing locations (which, I think, is how the network Location stuff was meant to be used anyway!) -- I rarely, if ever, had to explicitly pick a WiFi network once the Locations and Preferred Networks lists were set up.
In Lion -- not so much. It appears the Preferred Networks list is global -- shared among all Locations. I often have to change both the Location (which has things like proxy settings bound to it) and the WiFi network, which is a minor inconvenience at worst.
I don't see a logical, functional reason for this change, other than perhaps Apple targeting more casual uses who simply don't give a crap about such details.
Or it may simply be a little bug.
