Are you sure there was a 2006 TrainingCom seem to remember HeliTrainingCom 1/2005 said something like you have stated above.
However that AIC we keep talking about (72/2007) seems to imply that the new flying training requirements are a minimum of 2 hrs SEP to SEP, unless you are flying something not included in App1 to 2.245(b)(3), which in english is what we know as the single engine piston group. This means that Robinsons require 5 hrs of flight training (see below for the apparent get out).
There is however one bit I can't work out and that is that the AIC seems to imply that this may not be mandatory until next January, but I may have misread or misunderstood that bit. The AIC says that TRTOs CAN change their training manuals now but after January it will be mandatory.
Sorry to make things clear as mud again, but I don't think it quite as clear cut as it seems.
I know some schools are already applying the 5hr minimums for Robinson training. I don't know if this is by choice or necessity .
