For a February use year, those owners have already lost the max benefit for this year if they were going to add today.
So, let's talk about a March UY first instead- if a March owner chooses to buy direct points today, they would get March 2025 points for free, and then on March 1, 2026 they would get their 2026 points. If they bought 150 points, within a couple of weeks they would actually have 300 to spend (2025 points banked forward and the 2026 points).
The February UY owner, if they chose to buy direct points today would get February 2026 points. They would not get 2025 points.
That is why the advice is to buy just before your UY. However, life doesn't always work that way and if you buy today, at least you've avoided the price increase coming tomorrow.
