ref returns the base type that an object is, but not a package/object-type.

Reread docs :) . For blessed variables ref returns package into which variable is blessed.

Normally one uses ref with objects to check if they belong to some specific class and UNIVERSAL::isa with objects to check if they belong to some class or its subclass.
