I just made a test case and it does not work for me at 7.1 DB2 group level 30.
create table scott.junk1 (key1 char(1))
create table scott.junk2 (key1 char(1))
create table scott.junk3 (key1 char(1))
select * from (junk1 join junk2 using(key1)) join junk3 using(key1)
Name KEY1 is ambiguous.
If it works for Raul at some other level of the DB2 group then definitely you have a case with IBM.
