i would like to ask about something that Randal Schwartz( merlyn ) says in his book(Alpaca). he says

if we copy Gilligan's provisions: 
my $gilligan_stuff = $all_with_names[2][1];

[download]
then when we remove @all_with_names, we still have one live reference to what was formerly @gilligan, and the data from there downward remain alive.

i would like to ask reffering to the meaning of "downward". does it mean that all items with indexes like [i][j] with i=>2&&j>1 remain available ?

thank you
