They are the same method. Sometimes people will hold the yarn at a slightly different angle, and hook it with the needle in a more exaggerated way, but it is still called continental knitting. Some people will even "throw" the yarn around the needle, like in the English method. But if they are holding the yarn in their left hand, even this can be called continental knitting, although this is less common, and is not typically what people mean when they say Continental knitting.
Hope that helps.
