this assign the first field to the first field, so in fact it does nothing, except that it force awk to re-evaluate the current line ($0) with the modification that have been performed (here, shrinking of the last field)
sub(".*"$2,$2,$0)
substitue anything before the second fields AND the second field BY the second field ONLY, so in fact this delete the first field
1
the 1 after the } means "true" that means that all lines will be displayed
