All of the Olimex diagrams of the 20-pin ARM JTAG header are backwards when compared to the standard ARM connector. Am I correct, or am I missing something?

Depends if you mean the one on the board or the one on the tool.
I've used multiple JTAG tools (not just Olimex) with multiple Olimex boards and they all worked so I think Olimex have it right.

The connector is fine, the information is improper since the image shows the schematic and the PCB pads (as seen at the bottom "ML20PADS") and it should show either the connector that is led out of the plastic box or the cable. The way it is now - it is not user-friendly and perplexing. Thanks for the notice I will make sure to fix it.
Thanks for clarifying. I've got a ULINK2 and an Olimex ARM-USB-OCD on the way. I had to design an adapter PCB for a project I'm working on and was hoping that my pinout wasn't going to be backwards. Sounds like I should be ok. Thanks!

Since I just overwrote the original image with the same name, now your original post looks funny :)
