You are right about the abandonment. And, it'd be too far north/cold for them too.

Ignoring that, it'd be impossible for him to end up there like that. Not only is is a longer voyage - and they barely made it in otl - but the difference between the two is somewhere in the neighborhood of 3000km. There is no way on earth that they could blow that far off course and live.
