How does a split work at a parallel gateway (AND)?

In a parallel process pass, a process folder is split at a branch and forwarded via each outgoing flow. In the BPMN process diagram, there are three ways to do this:

Parallel gateway

As soon as a process folder reaches a parallel gateway with two or more outgoing gates, one process folder with the process number of the activating process folder is forwarded to the subsequent objects.

Activity with multiple outgoing flows

As soon as an activity is completed, one process folder with the process number of the activating process folder is forwarded to a subset of the following objects.

Process/Subprocess

Parallel activities or processes in a Process or Subprocess object are carried out simultaneously. As soon as a process folder reaches a process or subprocess, one process folder with the process number of the activating process folder is forwarded to each activity or start object of the subprocesses if they have been included in the simulation.
