It might have "worked" in the sense of not throwing an exception .... but it would have been semantically incorrect. That set mapping can only contain one element!

Here is an overview of the issue:
---------------------------------------------------------------------
        Key: HB-248
    Summary: Repeated column in mapping
       Type: Bug

     Status: Closed
   Priority: Major
 Resolution: REJECTED

    Project: Hibernate2
   Versions:
             2.1 beta 1

   Assignee:

Description:
Declaring in a mapping:

    <set name="employeeIds" table="owf_employee_region">
        <key column="employee_id"/>
        <element column="employee_id" type="long"/>
    </set>

Throws the exception:

net.sf.hibernate.MappingException: Repeated column in mapping for collection: bean.Region.employeeIds column: employee_id
        at net.sf.hibernate.collection.CollectionPersister.checkColumnDuplication(CollectionPersister.java:884)
        at net.sf.hibernate.collection.CollectionPersister.<init>(CollectionPersister.java:193)
        at net.sf.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:146)
        at net.sf.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:647)

I think this used to work with 2.0.2.
