Nothing contained in this paragraph shall be construed to prohibit a committee from adopting policies and practices with respect to the application of this section which are similar to the policies and practices adopted with respect to the application of section 705(c)(1) of Senate Resolution 4, 95th Congress, and section 72a–1d(c)(1) of this title.11
