The final parameter to substr() isn't needed  (and would only be "2" for what
you wanted)

Well, it's only printing the first field, not necessarily the field that
matched.
eg
  $ echo hello there everyone | awk '/there/ && /everyone/ { print substr($1,length($1)-1) }'
  lo

You need to do $1 ~ /regex/  if you only want to test against the first field
