Orbi Backhaul Configuration with 2 Satellites

[spas]

I purchased a RBK53 Kit at Costco with 1 Router and 2 Satellites. The picture below shows the QUAD STREAM 1733 Mbs/5Ghz configuration between 1 Router and 1 Sattelite. My question is, how is the backhaul configured when you add a second Satellite in a star configuration? Does it split the Quad Stream into 2 Dual Streams?Thanks!

My understanding just from pre-purchase resarch was that the MU-MIMO on the wireless backhaul allows full-speed communication to both satellites.
