If you can prove your trustworthiness with a GE card, they let you in. But you are not the person the line was created for. You do not have a NEXUS membership.

I guess I have to contact CATSA to clarify how I'm actually supposed to make use of this benefit as a non-US GE member (although I've also come across american GE members who've never received cards).
