New loop in dawObject

Hi.
Could you please explain me the meaning of the following loop added to drawOrigin function in objectDetail.php ?

foreach ( $list as $origin ) {
//$origObj=null;
$origObjClass=null;
$origObjId=null;
if ($list->originType == get_class($obj) and $list->originId == $obj->id) {
//$origObj=new $list->refType($list->refId);
$origObjClass=$list->refType;
$origObjId=$list->refId;
} else {
//$origObj=new $list->originType($list->originId);
$origObjClass=$list->originType;
$origObjId=$list->originId;
}
$gotoE=' onClick="gotoElement(' . "'" . $origObjClass . "','" . htmlEncode($origObjId) . "'" . ');" style="cursor: pointer;" ';
echo '</td><td xclass="noteData" '.$gotoE.' style="height: 15px">';
}
It seems that you loop through attributes of object $list ( $obj->Origin), then ,regardless attribute, you test $list->originType and $list->originId (that seem to be a copy of arguments refType, $refId) and echo an onClick action gotoElement to the same object once for each attribute.
I'm missing something.
Thank you for your attention
