I agree with you. If the unit doesn't overlap another at the end of the move it's ok.
But , ( because with me there is always a "But"

)
for the artillery ( And only for it , not for the infantry unit in the previous diagram) i don't see what is wrong. The artillery, made an "reorientation" and at the end it doesn't overlap the infantry.
If the infantry made also a reorientation , i agree these two units overlap each other. So No . For the artillery only , no issue.
