May be able to take photo later but not now.
Hope you can understand my poor description.
The quick advice is, forget about the blue arrow (wrong for the R-side), imagine you have L-side installed as in your 2nd photo, place the R-side bracket next to it with both spring nuts at the same height and both nut positioned towards the front of the car.
In the 2nd photo, the spring nut on the L-side is inserted from the front towards the rear of the car.
In order to achieve the above condition, the R-side bracket has to be positioned in a way with its spring nut inserted from the rearend towards the front of the car, opposite to the L-side.
May look asymmetrical but they are not.
As in your 2nd photo, the opening/concaved section of the plastic bracket (hidden in this photo) is facing forward for the L-side.
However, for the R-side, it's the opposite and the opening/concaved section will face the rearend.
The L-side is fixed by the horizontal bolt screwed in from the rear to the front (as in your 2nd photo) and thus, don't forget to install it before setting the bumper beam on the body side.
If you imagine the 3rd photo was taken for the L-side, the blue arrow bolt hole position is correct for the L-side but not for the R-one.
For the R-side, the bolt hole is not at the blue arrow.
It's vertical direction from the bottom to the top at the tow hook.
In fact, just for the R-side, you can leave it on the body side and not on the bumper or not even install it until the very end.
