It is showing you the plans for each view in the query. When trying to 
specify your own plan, you can only specify *one* as far as I know - for 
your own query, not the underlying views.

So likely this would be ok:
 select * from
 XXX B
 PLAN (B NATURAL)

However, you really should not be specifying your own plans. In almost all 
cases a query can be optimized simply by adjusting the structure or by 
adding appropriate indexes. Using you own plans should be ab absolutely last 
resort only.
