I think CONF iture's point is that any deviation from 'en route de vol' should have been mentioned in the report. The motivation is not known, but isn't it established deviation is PIC's discretion? Also, 3nm in 119 appears to be a straight line and gentle course, who is to say the 3nm does not represent a 60degree left turn, made in urgent fashion?
Also, my understanding is that 'present the document' means would Capt Bob produce a report of accident without the notation of course discrepancy?
