109 front 11" brakes conspiracy

With all the trouble bleeding the brakes, I have been going by the book putting everything back the factory way.
Here is something strange, if you google around for pictures of the front brakes, 109, leading, trailing shoe, etc you will find a ton of pictures with the back plate so the dual slave cylinders are vertical. One on the top and one on the bottom. The bleed screw is on the bottom slave cyl.

The 3 books I have been referencing seem to show it the other way. Each slave is horizontal with the connecting line running over the top of the axle. To me this seems logical and would be easier to bleed. I however followed the heard, put the back plate on so the slaves would be vertical, and did it like the pictures on google.

Anyone else notice this. I attached one image from a manual to show. You see the numbers are sideways, so rotate the image so the numbers are the right way.
Edit: added another picture

Mine are top and bottom. All I have to work out is what they are off

The illustrations in the workshop manual have the top and bottom. I think it's a common lurk to swap them so they're horizontal to make bleeding easier. So long as the flexy is going to the top (point of least movement) I can't see the problem in having them horizontal...
