I answered a similar question in a different post, so rather than post again, I'll just reference it here:

Points represent two things, and those two things are inexplicably linked:
(1) They represent your % ownership in a unit
(2) They represent points needed in any given season to book a particular Vacation Home Villas
An important consideration is that a unit may compromise more than one Vacation Home Villas.
That consideration is important from a legal standpoint -- and to the question as to whether or not they can move points from one Vacation Villa Type to another - because when Disney balances point charts for the year, they must do two things:
(1) Ensure the total number of points required to book the entire resort remains the same as the total number of points declared in the resort
(2) Points continue to represent the % ownership interest, which means ensuring the total number of points to book a UNIT (not villa) in a given year equals the total number of points that unit represents (based on declaration).
We talk a lot in these boards, and when it comes to point charts, about #1, but #2 must also be true.
So while your 100 points and my 100 points may allow us to book the same number of nights in a specific VILLA TYPE in the year, #2 is *not* the same: their reallocation of 2BR into THVs to raise THVs has made it so that my 100 points no longer represents my ownership interest.
I can understand why it may seem like "why does this matter? We both can do the same thing with 100 points" it matters to settle the question of whether you can take points from high point villas and move them into, say, studios. This is an especially important matter for owners at places like PVB and CCV, where point-hungry Cabins and Villas exist, and where it is important that, say, studios don't become a dumping ground to lower the cost of bungalows/cabins. In the case of THV, what they did is illegal, because my points no longer reflect my ownership interest. (And given that I bought into SSR to stay in Treehouse Villas, ensuring that the
point chart for THVs represents THVs and not THVs + points used to lower 2BRs does matter to me personally, though I can get why people who may love 2BRs and love that Disney lowered 2BR costs may not be happy if this is addressed).
Now, I believe that all of SSR units are EITHER 2x2 THVs *or* 2-BRs, and that all Studios and 1BRs at SSR are, in fact, lock-offs. If that's true, then it may be possible in SSR to move points between Studios, 1BRs, 2BRs. I would in fact have to go look at the master declaration to see what the unit makeups are, and if all SSR units are 3-2BRs. However, they cannot reallocate points between THVs and 2BRs because of the requirement that points equal % ownership.
But other resorts - say, for example, CCV, where a unit might be a cabin, or in the case of some of my contracts, one unit is 2 Dedicated 2BRs; another is 1 LO 2BR and 2 Studios; and another is a Dedicated-2BR and a LO-2BR (and my % of ownership varies even when the # of points is the same, due to the size differences in units), the point allocation probably requires points to remain within vacation villa types in order to ensure that # of points = unit % ownership
