A coworker of mine copied files from one location (our released documents folder) to another (his local working directory). He copied three files (copy and paste in windows explorer), an assembly and two part files. They were all in the same directory on the server, and he copied them to the same directory on the local drive.

When he opened up the assembly locally, it still opened the part files off of the server. So then when he modified the parts/assembly, it modified the released document (which wasn't write protected).

Now, we already discussed using Pack & Go. What I am concerned with exclusively, is that this is not the functionality as expected. I remember hearing that SW2013 has different file reference lookups, but I could not find information on that anywhere. All the users here are expecting for SolidWorks to look in the local directory for the assembly first, is this no longer the case, and where can I find the information showing this?
