That's correct, that thing shows how much electricity is has been used since your last charge up until you switch to range extended (gas) mode.
If you've ever driven someplace, charged, and then unplugged before completing a full charge, you'll notice that it will keep going until you've used all of the electricity you added, so you'll get numbers like 14 or 15+ kwh
The same thing is true for ERDTT, since you're not technically in range extended mode, the electricity that the engine generated is added to the total.
Preheating does the same thing, specifically if you pull the plug prior to it completely topping off the battery. Again, the counter doesn't have the opportunity to reset itself.
