From what I have read to make an Inbred Line, you need two parents ...a male and female. So technically, you can't make an IBL with a clone only strain.
He outcrossed to a NYCD which actually has no diesel in it. Inbred lines usually lack vigor. Two ibl's crossed together make f1's which have "hybrid vigor".
Now since ECSD is really an accidental polybrid, you can't say it's true breeding.
If he were honest he would say that he made a hybrid using an ECSD clone and with outcrossing and backrossing he made a new line that had many features of the original clone. But he hyped it in a different way.
ICmag censors any discussion that would be bad for business, but who cares anymore,, their days are over as the people who have wised up come here. This place is sucker free. Look around at all the former members who are here and other sites.
If you get good weed out of it great, I wish I did, I had bad luck. But I made some crosses with my males to other sativas and a blueberry clone to make my money's worth.
I guess since it's an unstable polyhybrid ( otherwise there would be very little variation) and not an IBL , you may have to grow out a few packs to get what you are looking for. I've been offered some SD"IBL" clones, but I'm happy with what I've got.
I bought it to see for myself and had bad luck. I'm sure it happens from time to time with any breeder.
