What I mean is it seems rather long. I thought the grips were usually relatively short and the idea is that one would actually grip the pommel, i.e.:

But I'm not super familiar with Viking era swords so perhaps there was a lot more variation in grip length than I am aware of.
EDIT: Or perhaps the pommel is actually incomplete and the bottom of it has actually moved up the tang over the years?
