Stateflow event will start a new process?

When adding code on a transit between two nodes in a stateflow chart, one can mix statements with events such as a trigger to a block outside the chart.
For pure statements I know that they will be executed sequencially. If a trigger inserted between two statements, will the next statement wait for its turn until the trigged block finishing execution?
Or the event will start a new process/thread (for the trigged block) which will run concurrently with the stateflow chart?
Thank you for your time!

This is a good question. I remember we had to find this out when someone made a C code S-function accessing shared memory data. The S-function is triggered by an event during a transition. To be honest, I don't remember the conclusion any more. What I can suggest is that you make an example to test it out. Simulink has debug capability so you can actually run simulation step by step. You can find out the execution order. I think that will be the most convincing evidence that you can rest on.
