How do I get an IIS application pool to not start when it is created by Otter?

(Crossposting from StackOverflow: http://stackoverflow.com/questions/35420483/how-do-i-get-an-iis-application-pool-to-not-start-when-it-is-created-by-otter)

Note: I'm very new to Otter script so if this is simple then I apologize in advance!

Here is the main nugget of the script I've got now:

IIS::Ensure-AppPool(
    Name: LonTest,
    Credentials: SVC_LonTest1,
    AutoStart: false,
    QueueLength: 1500,
    Pipeline: Integrated,
    Runtime: v4.0
);

Otter does create the app pool, but it is always started even though the docs seem to indicate that "AutoStart: false" should change the value of the "Start application pool immediately" checkbox in the Basic Settings of the app pool.

What do I need to do here to make sure that value is unchecked and that the app pool is initially stopped when it is created?

PS: Otter is not an option in the list of products on this forum ;)

FYI one of our developers posted an answer on the linked question.
