you're right, is interpreting, extract the (row, col) position, although the output at(a,[0,1]) is very confusing, is not a real pretty print as it appears in math textbooks, the hp-prime development team is not interested in improving this, I think it's too simple to improve history view, 100% pretty-print

a:=[[9,8,7]];
a[[1,2]] -> 8 // ok
or
a[1,2] -> 8 // ok

purge(a)
a[1,2] -> at(a,[0,1]) // ok but incomprehensible to an inexperienced user

... but in other cases as:
a|x| [enter] returns aABS(x) ?? must generate a syntax error or made implicity multiplication, agree?
