Unclear documentation: Why are commands run in parallel on remote?

[rmplbv]

The documentation (README.md) says 'Commands in remote flights are executed in parallel against remote hosts.'.
Is this true?
If provisioning a host or actually doing more or less anything on a host it's almost always a chain of commands depending on a specific order. Even the example in the README depends on specific order of commands.

If this is not true, can this be rephrased, so people actually dare to use flightplan?
