I'm afraid you'll need to use another regular expression to get the repeated subpattern matches. So, you could do something like this:

preg_match_all("/(?:S|R|B|O|A|K|H|P|U|i) +(?:IA|E|N|) +[0-9.]+\/[0-9]+ +via +([0-9.]+), +([a-zA-Z0-9.]+|), +cost +(?:[0-9]+:|)[0-9]+, +age +[0-9]+ +\n((?: +via +[0-9.]+, +(?:[a-zA-Z0-9.]+|) +\n)*)/",$s,$matches,PREG_SET_ORDER);
foreach($matches as $id=>$match)
{
    unset($matches[$id][0]);
    if(isset($match[3])) {
        preg_match_all("/ +via +([0-9.]+), +([a-zA-Z0-9.]+|) +\n/",$match[3],$subpatternMatches,PREG_SET_ORDER);
        unset($matches[$id][3]);
        foreach($subpatternMatches as $spmid=>$spm) {
                unset($subpatternMatches[$spmid][0]);
                $matches[$id] = array_merge($matches[$id],$subpatternMatches[$spmid]);
        }
    }
}

Which gets the following data for your example file:

array(4) {
  [0]=>
  array(6) {
    [0]=>
    string(6) "10.140"
    [1]=>
    string(8) "bond1.30"
    [2]=>
    string(6) "10.141"
    [3]=>
    string(8) "bond1.31"
    [4]=>
    string(6) "10.142"
    [5]=>
    string(8) "bond1.32"
  }
  [1]=>
  array(2) {
    [1]=>
    string(6) "10.140"
    [2]=>
    string(8) "bond1.30"
  }
  [2]=>
  array(2) {
    [1]=>
    string(6) "10.140"
    [2]=>
    string(8) "bond1.30"
  }
  [3]=>
  array(2) {
    [1]=>
    string(6) "10.140"
    [2]=>
    string(8) "bond1.30"
  }
}
