In the clip, you can see Bedard purposely shoot the puck high on
Linus Ullmark from a bad angle in an attempt to create a rebound. That's exactly what happened, as the puck rolled back to Bedard behind the net, and before Ullmark realized where the puck was, it was too late to get set and Bedard had already swept around the net and tucked the puck into the bottom corner on Ullmark's far side.
