I would naïvely expect MODE=HOME to cause fewer hit rather than causing more.

The implementation covers such cases as where a program in address space A PC's to address space B and it is within address space B that the system found MOD1. Jobname applies to a workunit whether that work unit is running in the address space of the job where it started or with an alternate primary address space when following the chain of space-switch PC. The home address space remains the same. Since SLIP has no idea that you want to avoid this case (which MODE=HOME would so indicate) it treats finding MOD1 in any address space as having found a copy to use.
