Yes, but only for the number of points (plus or minus banking and borrowing) you own at each resort.......so for OKW you would have an 11 month window with just the 210 OKW points not the 60 BWV points, with the opposite being true at BWV.
You do have the 11 month window at both, but can only use the points at each resort at the 11 month window. So, you can only make ressies at the 11 month window using 210 points at OKW and using the 60 points at BWV. You can't combine the points to gain 270 points at either resort.
It is MUCH easier accomplished if the points are the same use year, and thus in the same account. If they are different use years, and thus two memberships, it can get complicated if you don't keep track yourself, and get an unhelpful CM at MS.
