Would like to ask whether the 10x swipe per month is also inclusive of supplementary card?

e.g.

Principal 7x swipe & Supp 3x swipe = 10x swipe. Will this be eligible for the cash rebate?

Or must it be it be principal 10x and sup 10x in order for cash rebate? If this is the case, can it be another option like principal 10x but sup 8x (in this case only principal eligible for cash back where sup is not eligible?)

Thanks
