Looking at the N&W drawings at the N&W HS, the left side lubricator handled the "Valve Oil" while the right side lubricator/s handled the "Engine Oil". There are drawings showing the right side with one and two lubricators and how their respective lines were routed in order to lubricate the engine (a drawing also shows left side lube line routing). The question is what changed on the right side? One possibility is that they found out that the one lubricator could handle it all with different distribution manifolds.

The mechanical lubricators MUST be separate, as valve oil wasn't used as machinery lubrication, and machine oil wasn't used for injecting into the steam flow for the valves & cylinders (valve, or 'steam', oil is water soluble). 

For now, the answer remains to be found.
