Just to keep from re-using variables (the variables for reading name/value/role). Forces us to re-declare the locals to the expected values (the variants) so they don't get accidentally polluted by prior tests. From a readability pt of view, also avoids having to scroll back up to look at how some variable was initialised.

It'd be straightforward to remove the scopes if you like that better.
