Before Perl executes anything it "compiles" it. This is how it finds all the syntactical errors in one pass rather than only as it executes various branches of code. "use" is processed by the compiler step so the related code, constants, etc. will be brought in no matter whether the use is in a brantch of code which is never taken or is in a bratch which is always taken. Basically, all the "use" statements fire. Require statements are executed (or not) as they occur during the execution of the program. You can chose amoung various require statements, you will always get the "benefit" of any "use" statement in the program.
