Modularity and serviceability. Some sub-boards are designed to be swapped as separate units without disturbing larger assemblies. The GS8 Sub PBA is arranged so it can be accessed, disconnected, and replaced through its own connectors and fasteners while the OCTA assembly remains in place. This means you can do the swap without disassembling the OCTA, which is why the statement is true. If the design required removing the OCTA to reach the Sub PBA, that would indicate a non-modular approach, but the standard setup supports independent replacement.
