I am not entirely sure what kind of radio fuckery happens, but my phone (Oneplus 6 with LineageOS) can be connected to a 5 Ghz wifi network and have a 5 GHz hotspot open at the same time.
I am assuming the wifi chip has two (or more) somewhat independent frontends, since my home wifi and the phone hotspot are on two different 5 GHz frequencies.
