Yes thats true, however i am still not sure if i can repot in summer? Because spring is nearly coming to an end
I repot in every season. Main thing to worry about: Is the tree strong, and how much damage will I do to the roots. If you are just going to take it out of container A, and put it in bigger contaner B without doinbg anything to the roots, there is nog reason why you can't do that any time of the year.
