What was the significance of the parentheses? That is, how are they acting upon the expression in a way that would be distinct without them? Is it entirely so that the \1 knows what to refer to?
forward reference
\1 is the first
\2 is the second and so on
example:
FN LN:
(.+) (.+)
want LN, FN
\2, \1
