It sounds like he's talking to investors and not to general public.

In my experience in corporate america you communicate efficiency by proclaiming a checklist of things to do - plausible, but not necessarily accurate things - and then let engineers figure it out.

Nobody cares of the original checklist as long as the problem gets resolved. It's weird but it seems very hard to utter statement "I don't have specific answers but we have very capable engineers, I'm sure they will figure it out". It's always better to say (from the top of your head) "To resolve A, we will do X,Y and Z!". Then when A get's resolved, everyone praises the effort. Then when they query what actually was done it's "well we found out in fact what were amiss were I, J K".
