See my other reply, but I would not consider moving to the wrong side of the road to be changing lanes in the sense of requiring a signal, because you would never normally drive there. But in this case the driver sounds like an absolute nutter and so giving him as much warning as possible with signals and the like was probably a Good Thing.
They (the DSA) ARE teaching people to pbutt moving vehicles without indicating because having too many situations where one is indicating makes it less clear what the signal means. If the pbutting involves a lane change (ie into an adjacent lane in the same direction) then you indicate because changing to an adjacent lane in the same direction of travel is one of the situations where you must indicate. The fact that someone might be doing this to pbutt an obstruction becomes moot, as far as the signal is concerned. All other pbutting is usually done with good road position in advance.
The situation you are describing is something different - if cars are swerving then, regardless of whether indicators are used, that is bad because that is not adopting good road position in advance. It's not the current policy which is at fault but those particular drivers who are not attending to the road ahead.
