The 6+2 board uses a chip to double the ancient 3+1 design its not a "true" 6+2.
Ergo, any board has "true" phases, just not separate independent control, which really, is only important for power-saving, not power-delivery.
(4+4+2) means that of 8 phases, each are grouped in pairs so that only a pair can be shut down when not needed. Input driver, MOSFET, chokes and caps are all still there. This means you could have just two phases going, or 4, or 6, or 8, but not 1,2,3,4,5,6,7 or 8.
