Can only one error / success function be assigned for AngularJS $http promises?

try{
  try{
      var res = $http.getSync("url");
      res = someProcessingOf(res);
  } catch (e) {
      console.log("Got an error!",e);
      throw e; // rethrow to not marked as handled
  }
  // do more stuff with res
} catch (e){
     // handle errors in processing or in error.
}

$http.get("url").
then(someProcessingOf).
catch(function(e){
   console.log("got an error in initial processing",e);
   throw e; // rethrow to not marked as handled, 
            // in $q it's better to `return $q.reject(e)` here
}).then(function(res){
    // do more stuff
}).catch(function(e){
    // handle errors in processing or in error.
});

$http.get('https://api.github.com/users')
  .then(function (response) {

    var data = response.data;
    var status = response.status;
    var statusText = response.statusText;
    var headers = response.headers;
    var config = response.config;

    $scope.user = data;
    console.log(data);
});
