Just to "quantify" this...  Say you have N "spec sections" in the sense 
of testable normative requirements.  That's N single-section tests.  If 
any time a normative requirement applies only N/M of the remaining ones 
do, that's N^2/M two-section tests.  In practice, N is a pretty large 
number (in the hundreds) and M is somewhat smaller than N, so if you're 
doing a decent job of writing tests you end up with a lot more tests 
testing interaction than testing a single normative statement.
