A friend of mine released a game that sold around a million copies in the late 90s or early 2000s sometime and had a deal like that. Except the publisher claimed that after all the distribution and physical costs the profit of the game was 0 and so he never got any money from his profit sharing agreement. Steam and online distribution in general is a godsend.
