Adding Additional SRS60

I'm looking at adding at additional SRS60 to my Orbi Pro network 

The two existing Satellites are connected wirelessly to the Router 

I'm considering adding the new third satellite by Ethernet - The Wifi in this part of the house is already weak but I have an available Ethernet Cable, fed directly from the Router, to that area. 

There is no conflict with having one (only) staellite be ethernet connected backhaul and the others wifi, right? 

And the media center that was previously supplied by the dedicated ethernet, can be connected again by ethernet to the new satellite - the only difference is that it will now be sharing bandwidth with whatever wifi devices are being routed through that new Satellite. 

Have I got that esentially correct?
