This strengthens very little.
It is not as if David Innes referred to any specific part of the release and he only made the referral orally and in private and not in a public forum or in writing.
All it confirms is that NWBO has not changed any of their already vague guidance and with NWBO the devil is definitely in the details.
For example, the last time NWBO published an article, shareholders waited with bated breath for months, only for publication to take a very long time and when the article did come out, it was with a whimper in a lower tier journal. It made all the discussion of NEJM's and Lancet's publishing schedules at the time look pretty ridiculous.
