Oy, you're 100% right and that material is 100% wrong.
The Earth's gravity exerts a torque on magnets. Depending on where they are and how they're oriented, that can either repel them or attract them. They will tend to rotate to the orientation that gets pulled toward the stronger field, which tends to be lower, but it's not the same as gravity. The force does not generally point directly toward the middle of the Earth.
We've heard of a lot of problems with school material but this sounds like one of the worst.
It's so bad that I'm skipping our usual vetting step and posting this right away.
