Hey Samus, everything alright?
The plugin uses the RPG Maker's basic settings to define how the time bar and turns will behave. The pause mode freezes the turn bar's progress at any time, regardless of the engine's settings.
It also serves as a way to stop the action at any moment so you can configure manual or automatic actions for all players, regardless of their turn. You can even configure an automatic attack or spell on the enemy's turn. Of course, this action will only be executed on your character's turn, but you can leave it configured.
Thank you for your comment and interest. Feel free to ask any questions. Let's make awesome games!
