OVRDBF - Record lock

I'm not understanding something with OVRDBF.
My desire is to loop through a number of libraries all with same file, and update them.
The below CL program sets the current library as it loops through a file listing the libraries. *(I would think this isn't needed with the OVRDBF but added as an extra precaution).
The rpg program that the below CL calls (VND040R) will check the record lock before updating the record.
What I have discovered is that if the file has a record lock in the first library, the log file is coming back showing the record is locked in every library. Which makes me think that the OVRDBF isn't redirecting to the library.
What am I doing (or assuming) wrong about the OVRDBF?
