Reasons for whether item is relevant for Embargo checking?

When checking the logs of export documents I noticed that some are not checked for Embargo and has the message "This item is not relevant for checking."

I understand that for SPL the document only checks whether the partners are blocked and does not always check against the master SPL unless there is a manual change in the document. However, I always assumed that the Embargo check took place on every document.

For example, I have 2 absolutely identical deliveries with same material, origin/destination region and country, same partners, etc. But for some reason they have different logs. One has "This item is not relevant for checking" while the other displays the embargo/SPL checks which are released.

Can anyone please explain this?
