This may be a new plan; however, the intent is to deny the minority caucus from  having any ability to stop majority spending by allowing a 50% vote instead of a 75% vote to access our savings..  Another means to this same send was attempted in 2015 by Chenault and his usual band of suspects when they were in charge: :

From a 2015 ADN  Article: 
"Taking $5 billion out of the earnings reserve reduces the amount the Legislature has available to spend, changing the calculation for accessing the CBR. With the Legislature then unable to spend the money now in the earnings reserve, it would have the key to the CBR's billions with which to balance the budget with only a majority vote in each house."
