I would imagine this has to do with the whole, "you can't override variables" thing that comes with a declarative language. Truly, if you want do to this you need to just change the variable names so they won't conflict with the facter values. This is the primary reason (IMO) that example42 use my_ to prefix just about every variable they use.
