How does that work in the light of STA MAC address randomisation during
the scan stage? As I understand it, such STAs only use their "real" MAC
address for actually connecting to the AP, but hide their identity in
probe requests. So a dual-band AP can't rely on a STA's MAC address
being the same in both bands.
