It is always the same when someone comes in and blows themselves up in a thread where things are being worked through.

The transition of Venus from left to right of the Sun is perhaps understood as a rare transit when it overtakes the faster moving Earth -

During that period the Earth is also heading in the same orbital direction but as it is slower, the faster moving inner planet will eventually appear preceding the Sun or as a dawn appearance.

An extended version of Jupiter's satellites as they move from left to right in front of the planet before moving from right to left behind their central planet eases any difficulty there may be as an analogy -

The real innovation is the transition of the background stars from left to right or a transition from an evening to morning appearance as it is this observation that proves the Earth orbits the Sun.
