No that is how the system works today. I would like, and have always wanted a way to disambiguate without creating a new title. There should be some sort of visual indicator that we are going up to the parent level without creating a sibling to the parent.
title: ships
p: ships travel on water
p: they are like cars but on water
title: motors
p: ships have motors
p: spin around
p: very powerful
p: ships can be used for many things
title: fishing
p: fish are in water, so the incentives are super-aligned
