🎲 Pirates Of The Caribbean Philip And Syrena Ending

At the end of the movie Pirates of the Caribbean 4: On Stranger Tides, Phillip is badly wounded and seems to be telling Syrena not to heal him but only to forgive him. She then drags him into the water and we never see him again. Am I meant to assume he's dead now? Or was there some symbolic meaning to this gesture that I didn't catch? wguaLhr.
