one of the keys here is that individual build steps can't call other build steps the way you might think of function calls in, say, C or Python. So a BuildFactory (and the resulting Build that happens at runtime) is always a linear sequence of steps.

The Trigger step [1], with its corresponding Triggerable scheduler, lets one build step call another sequence of steps (by referencing its builderName in the Triggerable configuration).

The example in the Triggerable documentation [2] uses "waitForFinish=True" to serialize all of the steps, but by adding several schedulers to the schedulerNames list, you can get your various platform builds to run in parallel.
