Tomatoes are naturally selfing, and so breeding by hybridization will encourage heterosis.
Selfing is a bit like making an F2 of a plant with itself, and so the results will depend mostly on how true-breeding the parent is. If the parent is not true-breeding then you will get variation in the offspring.
Selfing has never claimed to always produce offspring that match the original. People may have tried to make that claim about selfing... and they would be wrong in most cases.

My Pre-98 Bubba Kush S1s often come out very close to the clone. That is the opinion of many people who have grown them over at least a decade.Show me the selfed plant that matches the original then.
