It’s even a little trickier than that. If overall population is increasing then one offspring this year may lead to greater proportional representation in the gene pool than two offspring next year. What few people recognize is that the opposite can be true if the population is decreasing.
But I think the original post assumed “all else being equal”, to allow focus on the main points.
