new a,b;
public OnPlayerUpdate(playerid)
{
    if(IsPlayerInRangeOfPoint(playerid, 1.0, 1207.0170, -1333.9816, 13.3984))
    {
       if(!IsValidObject(a)) a=CreateObject(18646, 1207.5631, -1334.1051, 13.5816);
       if(!IsValidObject(b)) b=CreateObject(18646, 1206.5031, -1334.1051, 13.5816);
    }
    else
    {
      if(IsValidObject(a)) DestroyObject(a);
      if(IsValidObject(b)) DestroyObject(b);
    }
    return 1;
}

this is just a fix for your code
if ANY player IS NOT near that point ,it will destroy the object for all.
