If we interpret it that way then it's a great tell-tale sign of meng amendment as only a bargaining chip. The reason being how do you undo the spillover from 2020 - something that already happened and at least partially allocated. Second - the whole amendment is so onorous and clearly eggregious to GOP that they won't like one bit of it.
Finally - it's terrible that Indian congressmen/women are nowhere to be seen pushing competing amendments to secure interests of backlogged indians. Absolutely amazing to me. TBH the fault may not be theirs. Look the squeaky wheel gets the grease. May be backlogged EB-I is not making enough noise.
