files getting overwritten

Greetings.

I'm attempting to demonstrate how RPMs will save the developer's butt  
by not allowing a file to be overwritten and during my demo, PackageB  
overwrites PackageA's file

[root@webd-m01 ~]# rpm -q --whatprovides /usr/local/testfile
psi-test-1-dev
psi-retest-2-dev

what did I do wrong?

--specfile snippets
