In my opinion, it is likely to balance the front and rear tread heat to maintain balanced handling as the tires are worked up, especially since the G8X is carrying more weight on the front axle. Quoted from the video just before he talks about the staggered diameters: "It's the balance between front and rear tyres that is essential". It cannot be for absolute heat dissipation because they are offering 3 different front tire aspect ratios:
  • 275/40R18 with 285/35R19
  • 275/35R19 with 285/30R20
  • 285/30R20 with 295/25R21
I don't get the argument of heat dissipation at all. Bigger rims evaquate more heat. The higher side wall on the front end is common sense: it makes the dynamic behaviour (mainly understeer) of the front less snappy. Nevertheless a pro driver would probably prefer lower side walls for more traject precision. They optimised it for the occasional track hero I guess.
