Are Automatic Discount Codes treated differently by Liquid than Manual?

[VictoryStore]

I've been running into some issues that are making me curious about how Automatic Discount Codes are classified. Searching for the code on the order page doesn't return any results, setting up a trigger in Shopify Flow to look for the code doesn't execute, and when I edit an Order Printer template discount.code returns empty. 

Is it supposed to work this way? Is there a different variable for Automatic codes that I should be using, or is this just something that's kind of broken?
