メソッドMergeFromでは、translationstranslations_.Add(other.translations_);の値を追加するオプションを与えています。

[global::System.Diagnostics.DebuggerNonUserCodeAttribute]
    public void MergeFrom(LocalizedString other) {
      if (other == null) {
        return;
      }
      translations_.Add(other.translations_);
      _unknownFields = pb::UnknownFieldSet.MergeFrom(_unknownFields, other._unknownFields);
    }
