Does the arrow in Figure 9 and in Figure 25 about the holdup relationship of Same-Edge Capture Center-Aligned Output contradict each other in AN433?

No, the diagrams are correct. For same edge capture, you perform same edge setup analysis and opposite edge hold analysis. Figure 9 is not very useful since it's just showing what all the relationships look like. Figure 25 is what should be used. I also prefer the online training to this document.
