Subject: Hidden shape??

Smillie in "Some notes..." gives the following example of "under":
x=.1 2 3;4 5;6 7 8 9
(+/ &. >) x
which is
[6][9][30]  (that is the elements are boxed)

Now this is the same as
<@(+/)@> x
by simply using the definition of under.

However if one tries to see what "box" gets, like this
y=.(+/)@> x
and y is
6 9 30

so < y is
[6 9 30]

So we did lose some 'shape' information along the way. How can you
preserve it?
