I'm far from sure what lies were told about this episode to who and by whom. Someone was surely lied to, but Hydrofusion are still (as of Stockholm at least) on good terms with Rossi, so it's a bit of a mystery.
Entangling Rossi deceits is pretty difficult. In this case all we know is that either he lied, or he lied saying he lied. In both cases to (different) business partners. Personally I think he just says whatever fits his current story, and assumes no-one will worry about inconsistency with the story 12 months ago. It seems to have worked out ok for him so far.
