I'm not a pilot but whenever I have flown into Eugene from California or Salt Lake and the wind has been from the south, the pilot has flown more or less up I-5, then turned west and then south over Halsey and come in from the north across Junction City, presumably in order to land into the wind, essentially the same as this plane did.  I think that is a normal approach when there are strong south winds, but I'd be happy to have a pilot or ATC comment on this.
