An interpretation of this would be:
Pick your rotation around ONE axis
You will affect two of the three axes
Rotation about a 2D space, keep other one constant
In short, you are working to rotate utilizing two axes at a time (mini-proof is notice the columns with the 1s and the 2D rotation like elements in the matrix)

For Ry(α), where would the red arrow go? And how about for Rz(α). Why does the top-right sin(α) in the second matrix lack a negative sign?
