Intent. This is a prep session for the 1600m time trial next week. It’s a good opportunity to see how your planned target pace will play out over a longer distance. If in doubt pick a pace you’re mostly certain you can keep ( = realistic pace). If you won’t be able to hold it here (or just barely survive), you will need to adjust your plan for next week.
Breakdown. 1000m @ mile pace is to get your mind and body ready to endure your target pace next week. The broken down 600m will help you feel the almost inevitable pace changes you’ll have when running the full 1600m (so you can adjust to stay on your pace next week).
