Lorenzo is on record saying that Marquez may have spared him a possible pass at Valencia "to keep the title in Spain". This was also the impression of most observers. Again, not illegal, and motives cannot be proven, -- and Lorenzo's title was deserved anyway -- but this is what he said, and to an extent what happened at Valencia substantiates Rossi's "accusations".
I bow to you on Italian idiom obviously, but didn't know you were an expert on Spanish idiom in addition, and if the initial statement was in his non-native English the same potential for misunderstanding exists for him as for Valentino, except Valentino is much more adept at English. My understanding of the comment which I have only seen in reports was that he was saying MM refrained from attempting a risky pass which might have taken Jorge or both of them out, as he did at PI btw.
My post in any case was in answer to another poster who was suggesting Jorge shouldn't be believed rather than the reverse, and concerned what Jorge had said about PI or Sepang which should be disbelieved.
