Since you didn’t schema qualify the sequence name every single time a
default value is created the sequence will be looked up anew. The stored
expression is not associated with any specific object.

This is also why there is a separate step to mark a sequence as being owned
by a table. That establishes a dependency that this textual form is unable
to do.
