The X, Y, and Z values in the dialog are not a matrix row. They are the coordinates of one endpoint of line segment representing a vector. (The other endpoint is implicitly 0,0,0.) The direction the vector points defines the axis of rotation, and the rotation angle defines the magnitude of the rotation. Note that the only thing that matters for this vector is the direction it points, not its own magnitude. So, 1,0,0 and 2,0,0 would produce the same results for a given angle, since both are aligned with the X axis.
