What is the impact of enabling the " Use Interim Cash Account when Cashing on Due Date" option?

If my understanding is correct, this field is set to "YES", check remittances are posted to a temporary account; when set to "NO", they are posted directly to the cash account.
However, since the posting type used is always PP28, I’m struggling to see the real operational difference.
Could someone confirm if this understanding is accurate and clarify the use case for activating this option?
