The 3 radios are for 2.4GHz, 5GHz and 6Ghz.
4x4:4 means 4 transmitters x 4 receivers and 
4 simultaneous transmissions per client.
(Thats what I gather from further reading.)

You're right. The numeral 4 caught my eye and not the 'three' and I didn't take enough time
to read thoroughly. Anyway 3 is still getting heavy on radios.
