That's strange -- it seemed like there was a catch built in so that the pin wouldn't pop all the way through. I'll have a look at it tonight and verify, but I don't see any other way to remove those without pushing the pin.
Edit: Yeah, it should catch when you push it through.

I went through the seat/panel removal blind yesterday and everything that I learned looks to be covered in here with multiple pictures and arrows. I'd say it's super effective.
