Interactive Build Orders

I've recently decided to check out the mod Interactive Build Orders in order to see if I could improve my gameplay. But upon going through around 6 of them I've noticed a run on theme.

Part way through every build order you will get pop capped because the build order just stops telling you when to build houses. While this is a minor thing and you can learn when to build them. As this is a build order that goes specifically to castle up. You would think that the build order would have specific timings of when to build houses all the way through. Not just into feudal age.

Am I wrong in thinking this?
