v8i - UCF vs PCF

Question

I noticed that if I placed a configuration variable in both the UCF and the PCF, then the UCF was "cancelling" the PCF. In both files, I was using the ">" sign to append the definition. 
 For example, I had MS_MACRO defined in both, using the ">". The result from the UCF showed up during checking, but not the PCF. If I commented out the UCF definition, then the PCF result would show up during checking. 
 Has anyone run into this before?

User-level configuration variable settings take precedence over all other level settings. 
 
 Edit: A bit more information from the V8i help file.

Project-level configuration variables are the fifth to be processed (after user-level configuration variables). They are usually set by a site or project manager to facilitate using the application in workgroups. Settings made at this level can be overridden by settings at the user level.

User-level configuration variables are the fourth to be processed. The user configuration file determines which project configuration file is processed. User-level configuration variable settings take precedence over all other level settings.
