What exactly do you mean?

In the second example;

sequence seq
seq = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}}
integer a
a = seq[ {2, 2} ]

to me it reads, "an embeded sequence", eg 'variable a' returns {{2,2}},
where example 1,  'a' would return
'integer 5'.

n.b. You can do what was done in your example by doing the following,

sequence seq, b, a
seq = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}}
b = [2][ 2]
a = b
