How did another amendment made by the Constitution (Forty-fourth Amendment) Act, 1978 affect this clause?
The Constitution (Forty-fourth Amendment) Act, 1978, omitted the protection of the President's salary reduction from clause 3(4)(b). This means that during a national emergency (Proclamation under Article 352), the President no longer has the power to issue directions for the reduction of salaries and allowances of all or any class of persons serving in connection with the affairs of the Union, including Judges of the Supreme Court and High Courts.
