Shrimp are detritivores, they don't attack alive things so I doubt it dove into a swarm of worms and attacked them.
Are you sure the worms are planaria? I've had many different kinds of worms that I thought were planaria, but turned out not to be. There is pictures and I believe even youtube videos people have posted of planaria attacking and killing shrimp.
Maybe it is only one kind of planaria worm that we identify as the shrimp attacking kind, while the true meaning of planaria is the entire group of certain kinds of flatsworms, as some can live on land, in moist areas, dry areas, some are underwater, some are freshwater, some are saltwater, so perhaps us "shrimpers" use the term more specific for a certain kind common to freshwater tanks and being submerged that attack shrimp, but it does happen.
You have many other worms or they just didn't get to attack the shrimp, but I still highly doubt the shrimp went after worms, they were alive.
