Yeah I thought they looked a bit odd at first to. I thought it would
just get rid of the duplicate NOTICES's.  On closer look they don't
NOITCE anymore because all the tables are listed in the drop.  Here is
an example:

# with all them in in drop table
create table test (a int primary key);
create table test_a (a int references test);
create table test_b (a int references test);
drop table test, test_a, test_b cascade;
DROP TABLE

# now without test_b
create table test (a int primary key);
create table test_a (a int references test);
create table test_b (a int references test);
drop table test, test_a cascade;
NOTICE:  drop cascades to constraint test_b_a_fkey on table test_b
DROP TABLE

In fact you don't even need the cascade anymore if you specify all the
dependent tables.
So that certainly *seems* right to me.
