Does Connes spectral model solves the Hierarchy problem?

I was surprised to read that NCG model à la Connes still may suffers from the Hierarchy problem.

AFAIK, in the Spectal Model the Higgs and top quark masses are computed. So they are direct consequences of the few hypothesis of the model and are in line with experimental values.
I would say there is no Hierarchy problem anymore, since the low mass of the Higgs (with respect to the GUT scale) is not unnatural and fined-tune anymore but "logical" because it comes from direct computation.

So, does NCG solves the Hierarchy problem?

BTW, a very nice introduction to NCG by Andrzej Sitarz
