Congrats to Hasselblad, they should be proud of this and be proud of the X system
That being said, these rankings/marks are fairly meaningless IMHO. Many of us have seen the 101 score for the 645z, and I'm sure the GFX and H5D-50c/H6D-50c/Credo 50/IQ123 50 would also perform just as well as the 645z or X1D (or better) according to the DXO marks.
I've been fortunate enough to own and shoot with the D800E, D810, A7RII, 645z, and now the X1D. They're all top performers according to DXO and excellent cameras, and there wasn't anything I could do with one that I couldn't do with another according to my shooting style (any limitations are based solely on lens selection between MF and 35mm). When I was generating revenue with photography, it was with Nikon. As far as awards go, I recently had an A7RII image that was a finalist in a big contest (1 of 49 finalists from 52k entries). For personal projects, last set of images was a full-spectrum A7R and 645z. I'm currently shooting with the X1D and love it. The only image of mine that has ever actually won an award I took with a D300 and 50mm 1.8 D Nikkor, and any of the top DXO contenders these days are miles better than the D300. They're all great and I consider myself fortunate to be a photographer in an era where there are so many great options out there.
