Well, I'm not convinced by your source material, no. It's literally completely different to the situation unfolding. I'm going to do more research into the exact sort of damage an axe throw of this kind would do, but as I mentioned, in a charging situation they were known to completely destroy shields. The same sort of thing is expected from spear thrusts and javelin hits, if that makes it any easier to imagine. 

Sources I've found suggest the point and edge of a Francisca, which is roughly what Sigurd's axe is based off (the Vikings robbed the design off the Franks) could pierce chainmail when thrown. At the very least, they were renowned for shattering shields, so I think you may be underestimating the force with which the axe would collide with Gigue, particularly as his own momentum would be set against him. 

Here's probably the most detailed source I've found on throwing axes, which says they can pierce chain mail.
