My understanding is that it can't be branded Thunderbolt 4 because it only supports one external monitor, but that it's effectively Thunderbolt 4 in every other respect.
The technical explanation for the limitation of the built-in display support is that the base SoCs have one Thunderbolt bus that supports 2 display outputs, one of which is used by the integrated display.
This new “basic” “pro” has only two thunderbolt 3 ports but “pro” “pro” has four thunderbolt 4 ports.
Basic Pro even supports only one external monitor.
Basic Pro is very misleading people when they buy MacBook Pro.
