I do the same although I add aromatics like onion, garlic, and chili flakes. Steaming it in its own juices gives a more flavorful result at the end. I've never found octopus to be gamy in any way. Unless perhaps it has been dried, which can often be the case in a greek restaurant but that usually only results in a chewier texture, not a gamy flavor.
