I don't know how you conclude that considering when the two were both available for selection Mathers started at Full Back.
Would Roberts have started there against Hull and Cas if Mathers wasn't suspended ? - obviously it is only guess but I don't think he would have done.
The question whether he should be first choice would obviously yield an answer of yes, certainly given both his and Ainscoughs performances against Cas.
