Section 53 of the Companies Act: A Paradox of Corporate Law

I'm really getting confused with Section 53 of the Companies Act. Kya aap jante hain? It says the company has power to transfer its undertaking to another company, but then it says the transfer can be made only with the sanction of the Central Government? So, are we saying the company has all the power, lekin phir woh power ko iske paas nahin hai? Yeh kaisa ho sakta hai? It seems to me, kuchh contradictory hain jo koi explanation nahin de raha hai. Maine bahut padha, lekin abhi tak mujhe yeh section ka koi clear concept nahin mila hai. Koi bhaap bhai koi solution hai ya toh main hoon hi galat?
