> SELECT * from table1 > FK JOIN table2

What if table1 has been joined in twice, to what table alias is table2 joined against?

Example:

   SELECT * FROM table1 a
   CROSS JOIN table1 b
   FK JOIN table2

Would table2 be joined against "b" or "a"? I would guess "b" and guess the idea is to always let FK JOIN join against the previous join?
