That's all true... but the writers are looking at it plot-wise and both of them fall flat. They started off as rivals trying to eliminate the other so they could win the million, to romantic rivals. Then they come back in TDAS, to resume their romantic rivalry to the point where they finally stop denying their feelings for each other and become and official couple. This was the span of two seasons... yeah they might still have a fixation for the money(it's Al and Heather) but it won't be as significant as it was before. That's why they most likely aren't returning for next season or else they'd be in fart balloons as well.
