For parallel path execution, please add a checkbox to the Action Set called "Enable Atomic Operation" - Any actions contained within the Action Set will execute without switching to another parallel branch. There are many scenarios that would benefit from this.

The actions in the parallel branches execute in parallel within the engine v2.
It's not executing each action at a time across the branches in a round robin pattern.
Please reach out if I've misunderstood the suggestion.
