This video is connected to Experiment 9 Cis/Trans isomerism: Maleic and Fumaric Acid. What your book (probably) meant is that the hydrogen bonds in fumaric acid, being intermolecular, does a better job of holding the molecules together, so it has a higher boiling point than maleic acid, which instead, displays intramolecular hydrogen bonding which doesn't hold the molecules together just as well.

The question remains why fumaric acid — which is definitely unable to build up intramolecular hydrogen bonds — has a higher boiling point, because in theory maleic acid should also be able to form as many intermolecular hydrogen bonds. Maleic anhydride-2-$\ce{C^{14}}$ is readily obtained from fumaric smaller dissociation constant for maleic acid compared to fumaric acid. Intramolecular hydrogen bonds do not have to be weak, but the strength of a hydrogen bond depends a lot on the $\ce{O-H\bond{....}O}$ angle.
