R-710 to R-405PD

So I was looking at the rudder today and following the plans. When I attached the R-710 to the R-405PD it made sense to me...Then I watched a video on this topic after going home from the shop and realized that it looks different.

I have the lip of the 710 inside of the 405. The video has it on the outer side.
I noticed this video is quite old so is this something that has changed or am just reading the plans wrong?
