Does AC3000 Mesh WiFi Range Extender (RBS50Y) work with the AX6000 WiFi Mesh System (RBK853)

I need to extend my network a bit and want to add the RBS50Y to my network.   Does it work with AX6000?  Does it require interface with the main unit or just another satellite. I have 4 Satellites.

It functions in extender mode but not in orbi mode. 

In extender mode it can end up connected to either the satellites or router depending on location/roaming.
