Question from the ignoramus, Re screw heads, what's the difference between Pozi and PoziSquare as advertised on Toolstations site or are they one and the same?

according to wikipedia...
The Phillips/square screw drive, also known as the Quadrex, Pozisquare screw drive, is a combination of the Phillips and Robertson screw drives. While a standard Phillips or Robertson tool can be used, there is also a dedicated tool for it that increases the surface area between the tool and the fastener so it can handle more torque.[58]
