Not able to get how the system is generating below Query

Question

I'm passing manual query with 1st table primary key = second table foreign key with left join but system generating in the logs 1st table primary key = second table primary with left outer join.. I Did 't get why this behavior comes.. Please any one can explain this one.

Manual Query:

select new com.app.model.EmployeeValues(emp.name,ed.permentaddres,ed.presentaddr,ed.qualification) from com.app.model.Employee emp left join com.app.model.EmployeeDetails ed on emp.id=ed.id where emp.name = :empName

System Generated Query:

select employee0_.name as col_0_0_, employeede1_.permentaddres as col_1_0_, employeede1_.presentaddr as col_2_0_, employeede1_.qualification as col_3_0_ from employee employee0_ left outer join employee_details employeede1_ on (employee0_.Id=employeede1_.details_id) where employee0_.name=?
