Is this the end of media training as we know it?

In the clip below Damon Green asks Ed Miliband a number of different questions about the recent teacher strikes.

Ed pretty much repeats the same answer 4 times, to Green's 4 different questions. 

This approach worked in the old world when the footage was cut for a 30 second TV clip. But when a full version of the interview finds it's way onto YouTube, Miliband ends up looking a bit of a plonker.

Does this mean media training techniques are being rapidly updated? Or is this simply a case of Miliband's poor execution?
