Yes, I am Paul. Generally, the 3D pdf shows what the model looks like when you create the PDF but in this case, the flexible subassembly constraints are broken. All the rigid subassemblies are copied accurately. Normally I use a minimum of fixed members and rely on constraints to one fixed member per subassembly to make changes and re-use easier. I am not expecting the PDF to be flexible but it would be nice if the hydraulic cylinders stayed where they were put. See the pink cylinders in the centre of this image.
