Well, they would have to BE in a hierarchy
or you would have to add the parent domain
to join them into a single hierarchy.

If you use public (Internet) names this is impracticable
since it would eliminate Internet name resolution.

In a private name space you could add the local.
zone above a.local and b.local, or even just having
a parent-child relationship, a.local and child.a.local.

But all this is something you have to plan ahead for
unless you are willing to give up general Internet
resolution.
