There is a difference between Ratcliffe saying it directly to the journos and Jassim's PR company leaking things into the press.
Deniablity.
Also, I don't see Ratcliffe's purpose in doing this interview right after the very high-profile meeting last week. If anything Ratcliffe and his team should be busy getting down to crunching out numbers to make the deal work.
Besides the hi-vis meeting, it is odd that he brought his two other partners into the meeting last week -- it seems like he has to convenience them of the potential of the project.
At this stage of the process, when you need to give a first official firm bid, you need the domain knowledge folks (financial and legal) involved who can do the due diligence and analyse to eventually come out with a bid. Not the C-suite folks who aren't the number crunchers.
Thus the cynicism.
