Don't know; only Current Use Year points are supposed to be transferred

that's why I said in my post that MS "has been known" to do various things where transfers are concerned. It may have been something to do with allowing you to take advantage of 11 mos home resort booking window on the transferred points, even though you are under no obligation to do that & as you said you can bank the transferred points to 2010 UY - - in July 2008 you could have reserved at 11 mos out at the transferred points HR for a trip in June 2009 - to do this the points would have to be 2009 Use Year points (or banked 2008 UY points) because the trip would be during 2009 UY (june 1 2009 - may 31 2010)
