Ah my bad, should have known better than to reply before investigating for myself. "together", was misunderstood as over top of each other rather than consecutively. The thought was that mapping only the ignition keybind was doing something with the play order because of the auto start (This is obviously not the case.) Now that I've looked at it: Both VS_INSIDE_ENGINE_STARTER and VS_OUTSIDE_ENGINE_STARTER were working for me, they are played prior to ..._STARTING. So the issue is not that anything is broken, just that the result you are getting is not what you expect. If I had to guess, this is how it was designed to function.
Thanks for your further investigation. I would assume, there is something wrong. In most Mod`s are the lines VS_INSIDE_ENGINE_STARTER= and VS_OUTSIDE_ENGINE_STARTER= either commented out, or removed. Maybe its because of lack of documentation...
