Description
In my opinion, rot_phi is to rotate the coordinate around X axis and rot_theta is to rotate the coordinate around Y axis. According to the formation of rotation matrix, the last matrix should be the rotation around Z axis intuitively. But what it does is to change the coordinate from [x,y,z] to [-x,z,y], which makes me confused. Could you explain what this matrix do here and why? Thanks a lot.

Research direction
No source file or test is named in the issue. Start by locating the code that creates spherical poses and applies the final coordinate transformation, then compare its rotation convention with the stated X- and Y-axis rotations. Done means clearly explaining what the [-x,z,y] transformation represents and why it is used.
