I think I don't really understand the question. I guess by basis you mean the axis of rotation? 0 -> x, 1, -> y, 2 -> z?

The order of concatenation of the matrices is determined by the order of rotation axes (xyz, yxz, ...) and whether it is an extrinsic or an intrinsic convention.

The yxz convention means that the first angle (alpha) rotates around the y-axis, the second angle (beta) rotations around the x-axis, and the third angle (gamma) rotates around the z-axis. When the extrinsic convention is used, you concatenate rotation matrices from right to left.

I don't know why you would want to change the order of arguments.
