Why was section 92 repealing the Maharashtra Housing (Regulation and Development) Act, 2012 provided under the Act?

The Maharashtra Housing Act, 2012 was received for seeking presidential assent under Article 254(2) of the Constitution of India, when the Real Estate Bill was not enacted. For the sake of uniform application across the country, the said State Act, was repealed under Article 254(2) proviso of the Constitution of India.
