If I understand that long winding article form the Aoko Aozaki page correctly, in order for the time travel changing past effect to remain permanent (instead of spring back after the fifth magic has finished activiating due to energy inbalance in the entire universe's timeline due to a massive amount of energy is used to move away energy that conresponds to the memory of Soujuurou and the time when Soujuurou is dead). These "segments of a timeline" which contains energy due to how the memory of  Soujuurou and the death of  Soujuurou is consist of many particles interacting has to be dumped somewhere, probably to obey the conservation of energy. Aoko than choose the dump them into the period where the heat death of the universe is

This action lead to the entire universe to have a new arragnement of energies (before the time travel, the energy arrangment in the unverse is like this ABCDE..., but Aoko's time travel cuased it to be something like AECDB...). Since such "misarragned" state is more likely to happen when the universe's energy rearranges slowly as it appraoches heat death (universe reaching equlibrium), it means the universe's progression to head death is pushed earlier

And for every subsequent use of the fifth magic the worse it will become seen a lot of energy is needed to achieve time travel and using the fifth magic. This extra burden of energy scramble up the energy distribution of the universe further (since it is more statistically favourable) resulting in a state closer to the homogenous state of heat death
