I see where you're coming from, but TB4 was the buzz of 2014. Back in the first 6 months, everything in the media was centred around AOD, and remained that way for a good long time until word got out that they definitely weren't pursuing for it. Since then, it's all been about TB4.
Questions would definitely have been agreed to, and at the time, AOD was the centre of the scandal in the media, so they asked, and he answered.
With so much happening since, people tend to forget what the news was at that stage. They asked what, at the time, was the big question people were asking, and Jobe answered openly.
Yes, I agree with all of that. However his purpose for doing the interview was to announce (unashamedly) that he'd used AOD, whether of his own volition or (more likely) at the behest of the club. IIRC he answered the other questions very, very carefully.
