Sounds like you've got it right. Be sure to only connect the same polarity binding posts with each jumper (red to red, black to black)! Then you connect your speaker cables still matching proper polarities (red to red, black to black) but one to the upper and one to the lower binding post. You are correct that AQ also recommends the diagonal connections but with the reverse diagonal connection of the speaker wires. Don't connect any wires across polarities, stick with matching the color connections for all wires and you'll be fine. Of course do this at your own risk, all standard disclaimers apply!
It's a bit more complicated in Nordost's explanation since their jumpers are directional, so they also indicate the proper direction for their connection.
