Summary: while loop through $branch doesn't show first branch

Initial Comment:
I try to xlog the URI's of all branches:

if (!lookup("location")) {
   switch ($retcode) {
      case -1:
      case -3:
         sl_send_reply("404", "Not Found");
         exit;
      case -2:
         sl_send_reply("405", "Not Found");
         exit;
   };
};

$var(i) = 0;
while($(branch(uri)[$var(i)])!=NULL) {
   xlog("----- branch $var(i): $(branch(uri)[$var(i)])");
   $var(i) = $var(i) + 1;
};

3 phones are registered. All receive an Invite. No problem there.
But this code prints:

OpenSips[6832]: DBG:registrar:lookup: found a complete match
OpenSips[6832]: DBG:registrar:lookup: setting as ruri <sip:testaccount at 4.4.4.4:30626;rinstance=30ffadee5f56a3d2;transport=UDP>
OpenSips[6832]: DBG:registrar:lookup: looking for branches
OpenSips[6832]: DBG:registrar:lookup: setting branch <sip:testaccount at 4.4.4.4:18349>
OpenSips[6832]: DBG:registrar:lookup: setting branch <sip:testaccount at 8.8.8.8:61002;rinstance=106001d34f5d2212;transport=UDP>
OpenSips[6832]: ----- branch 0: sip:testaccount at 4.4.4.4:18349
OpenSips[6832]: ----- branch 1: sip:testaccount at 8.8.8.8:61002;rinstance=106001d34f5d2212;transport=UDP

I would expect the output to be:

OpenSips[6832]: ----- branch 0: sip:testaccount at 4.4.4.4:30626;rinstance=30ffadee5f56a3d2;transport=UDP
OpenSips[6832]: ----- branch 1: sip:testaccount at 4.4.4.4:18349
OpenSips[6832]: ----- branch 2: sip:testaccount at 8.8.8.8:61002;rinstance=106001d34f5d2212;transport=UDP

I'm not completely sure but isn't every contact a branch, so the first one (sip:testaccount at 4.4.4.4:30626;rin..) also?
I use 1.8.2 svn9916.
