Sounds to me like the icon change is a fluke, but it's a harmless fluke since neither of the amphibious traits have an effect on units while they're on land. I think you have a good eye for catching it, personally. Two years from now a newbie will come into the forums asking this exact question, and nobody will know what the hell he's talking about, and he'll get probably similar responses. I call this effect the "Circle of Dominion".
