Jaywalking is any crossing in a wrong / illegal way, not about intersections specifically. Mostly it's about not using crosswalks, so I don't see how it collides with what Europe does.
In Europe you also have differences with some countries where crosswalk lights are as a mandate from God and nobody will cross even at 2am deserted road. And then you have countries where the crosswalk lights are mere decorations.
