I've used them for a few modules I've developed (see 
http://search.cpan.org/~brondsem/)  The modules are relatively small and 
I haven't used Devel::Cover in any quantitative way, just running 
`./Build testcover` and then checking the html output to see if I have 
full coverage in the methods I care about.

Regarding your example, I can't say for sure, but I think if you run a 
suite of tests through it at once, it will combine all the branch 
coverages together.  So you would get your 90% coverage metric
