Parallel to Serial Shifting-In with a CD4021BE Tutorial typo?

I am new here, so apologies if this is the wrong place, but I could not see how to email the author or comment on the page....
Anyways... on

The text says
Q8 (pin 3) to Ardunio DigitalPin 9 (blue wire)
but the circuit diagram graphic shows the blue wire to Q7 Pin 12 (but still labeled "3").
Assuming just a typo on the graphic, right?
