Let's take it logically.

Kalista starts with 2 stacks of Sentinel with 30s cd and a 60s recharge cd.

The recharge time begins when both stacks are depleated.

So, if she uses it everytime: W 30s W 30s W 60s W 60s W 60s and so on.

But she won't use it everytime so the cd can become again just 30s.

A soul sentinel lasts almost 1 minute so there can be 2 at the same time.

Two soul sentinels can be evaded much harder than one soul sentinel can be evaded by the enemy.

My conclusion is that the additional recharge timer limits the ability's moments of power.
