array faults?

Using arrays I came across some strangenesses. Probably this is well
known, but I couldn't find mentions of it.

I am under the impression that this should be an error. Am I wrong?

EXAMPLE 1:
maint=# select ('{{1,2,3},{4,5,6}}'::int[])[1][1:3];
int4
-----------
{{1,2,3}}
(1 row)

Shouldn't this have been just {1,2,3} ?

EXAMPLE 2:
maint=# select ('{{1,2,3},{4,5,6}}'::int[])[2][1:3];
int4
-----------
{{1,2,3},{4,5,6}}
(1 row)

Shouldn't this have been just {4,5,6} (or maybe {{4,5,6}} accepting the
result of example 1) ?

I am trying to do sth like:
maint=# select 1 = any ('{{1,2,3},{4,5,6}}'::int[])[2][1:3];
But that is not working for obvious reasons. This makes arrays pretty
broken for me.

Am I missing anything obvious?
