That's exactly what I was thinking. Open groups would be native to the area and therefore are just there. Other pre-determined monsters would have travelled for the purpose of whatever it is they set out to do.And looking at later quests/encounters, the traits do appear to be reflective of the area.
Again, my initial confusion could have so easily been avoiding. For example the text which reads "As you travel towards Arhynn" could have read "As you travel towards Arhynn from the east" and it would have made me notice the area.
Anyway, I feel more comfortable with it now :) thanks for helping to clear it up.
