They are 'free' only in the sense that they disappear after the battle where the rider dies.

Check Edi's DB, I don't think all units have upkeep free second form. There were some tweaks done that [at least to shapeshifting form of giants]. Best unit in that category is probably Cave Drake from LA Agartha's Cave Knight.
