For Example (using Parameterized Trigger for both):
Job A calls Job Util 1 and Job Util 2 as build steps.
If Successful, as a post build action, Job C is called to continue the pipeline.

The order of execution is Job A -> Job Util 1 -> Job Util 2 -> Job C.
The Pipeline Stage looks like this:
Job A
Job C
Job Util 1
Job Util 2

Is it a bug that they are not laid out in the order they are executed?
