pg_database datistemplate

Hello,

In the docs it is mentioned for datistemplate that

"If true then this database can be used in the "TEMPLATE" clause of
CREATE DATABASE to create the new database as a clone of this one."

However, one can create a database using as template another DB that has
datistemplate set to false.

In this situation, what is the point of having datistemplate?
