Will line conditioner do anything for the other receptacle in a duplex?

If a modular device (e.g., Venom Defender) and a whole house device (e.g., EP-2050) can "clean" the adjacent circuits, how is a power conditioner different?

My understanding is that the EP -2050 (https://store.acousticfrontiers.com/products/environmental-potentials-ep-2050) and perhaps the modular devices operate by serving as the preferred conduit for the noise in the signal. The EP-2050 functions in a similar way for surge protection. Any backwash, RFI, etc. that makes it to the distribution point (panel/outlet) Is essentially siphoned off preferentially, making it unavailable to other lines on the same circuit. This would be all circuits on the main panel for the EP2050 and the other outlet in the duplex for the modular device.  

I would think the line conditioner would serve as the preferred conduit in my case, leaving a cleaner signal to the other outlet. 

Theoretically correct?

I fully understand the benefits of and the principles behind the EP-2050 and a modular unit (e.g., Shunyata Venom Defender).  My question is whether a power conditioner has the same impact on the other outlet of a duplex, i.e., that it also functions in the same fashion as a modular unit.

On a dedicated circuit with an EP-2050. Please explain your rationale. 

Ironic. A Dayton SA1000 powering a  Romeyn DEBRA is what’s plugged into the other outlet.
