Please, help to understand ExecutorService#awaitTermination(timeout) behaviour.

I'm observing situation when I have in my code:

private void shutdownAndAwaitTermination(ExecutorService threadPool){
threadPool.shutdown();
try {
if (!threadPool.awaitTermination(threadPoolTimeout, TimeUnit.HOURS)){
threadPool.shutdownNow();
if (!threadPool.awaitTermination(60, TimeUnit.SECONDS)) {
logger.warn("Pool did not terminate");
}
}
}
catch (InterruptedException ie) {
threadPool.shutdownNow();
Thread.currentThread().interrupt();
}
}
Does the tasks in pool complete in this case before any other calls after shutdownAndAwaitTermination() in same thread ?

Looking into what is happening on production, I believe that the answer is no, but I just want to understand how to make sure that any code placed after call to shutdownAndAwaitTermination() will happen after last task in pool completes.

Thanks.
