in reply to regex only matching from last match

The match operator with the /g option will match all the patterns if it is used in list context.   However, when used in scalar context it iterates through each pattern in turn, which is what you are experiencing.

    Further to jwkrahn's reply, consider: 
    >perl -wMstrict -le
"my $str = '123 456 789';
 print qq{1st match: $1} if $str =~ m{ (\d{3}) }xmsg;
 print qq{2nd match: $1} if $str =~ m{ (\d{3}) }xmsg;
 print qq{3rd match: $1} if $str =~ m{ (\d{3}) }xmsg;
"
1st match: 123
2nd match: 456
3rd match: 789

    Try those matches without the  //g modifier.
