Fade to grey
The website does say they recruit DEC, it also says they have a policy of promoting from within! Historically they have taken a few DEC's on and I suspect that is why that it still there. At the top of the recruitment page (in red writing) it clearly states they are accepting applications for First officers, not DEC.
Like Deano777 says, I would be amazed if this happened. They are running a holding pool of about 50 (ish) SFO's who could slip into the left seat ASAP if required.
