Those 2022 UY points would not change use so they would only be good for trips during the 2022 UY of the points or banked for use in the 2923 UY of the points,
Now, depending on the UY of the person who gets them, they may be good for travel during someones 2021 UY, but the points themselves can’t change use dates.
You didn’t mention UY, but for example, if you had a June UY and transferred 2022 UY points to me into my Dec UY, they would be good from June 1st, 2022 to May 31st, 2023: unless the person banks Them,
However, I could use them during my 2021 Dec UY, as long as my trip was from June 1st to November 30th,
I could also use them for trips in my 2022 UY...Dec 1st to May 31st.
Basically, whoever gets the points just needs to have a trip during the time the points are valid for use.
