Swedish authorities share same (Site)Vision?

As previously noted, the web site of Swedish Customs has got a new design. The first thing that strikes me is how it feels very much like the design of another Swedish government authority -- The National Tax Board. Is this due to the fact that both use SiteVision as publishing platform? Many other Swedish government authorities use the same platform but have very different design so that's probably not the reason why.

My next thought is that it's a good thing. The likeness to the National Tax Board web site signals Government Authority to me and will probably help me navigate the site with more familiarity if the likeness is more than skin deep.
