Just for coverage and additional filling of minor pitting. I assume if you've got nice smooth grey concrete as a starting point, 1 coat may be good but I've found generally 2 coats is needed to hide the concrete (much like some wall paints, sometimes you can see roller lines or the substrate after 1 coat).
Plus the epoxies I've used spec a thinner first coat and successive coats are thicker. Zero chance the thinner coat level would cover the concrete to an aesthetically acceptable level.
But like you said, if you've got a top coat its generally doing all the protection from day to day wear/tear, so as long as the initial coat has a good bond and looks good to your eye, you should be good.
