As the esteemed Mr. C has indicated, in the general case it's all stock-standard with CSV ignoring the fact that aliases are involved. It gets a bit more interesting when the modules are marked as RENT. After a LOAD of FRED, there will be a minor CDE for FRED pointing to a major CDE of WOMBAT. This will occur even if the directory entry for WOMBAT was deleted before the LOAD. That is, the WOMBAT can be resurrected in the JPA, and even used afterwards, simply by LOADing FRED. The directory entry for FRED contains the name, addressing mode, and entry point offset for WOMBAT, so the directory entry for WOMBAT is not needed to make the major CDE. Now suppose JOE the other WOMBAT is loaded. Again we will get a minor CDE for JOE pointing to a different major CDE also called WOMBAT. A request for WOMBAT will find the most recently loaded one. At least, this is what happens when I test it.
