I trust that you thought you saw that, but bear in mind that satellite do NOT turn at all. The turns you see on Mercator projections are just that: projection artifacts. Circular low earth orbits (like the ISS) are great circles on the sphere. (The equator line is a great circle for example, but there an infinity of them, with various inclinations) The turn that you think you saw in real life is just a combination of perspective, optical illusion due to landscape or objects in your field of view, and your mental model of orbits making turns (which they don’t).
