Our organisation didn't receive this (to my knowledge) but I saw this thread shortly after booking a trip PER-BNE and return through corporate traveller. Clicked the sign up link, even though the flights had already been booked. My outbound (getaway) earned standard SC's, but return Flexi via MEL earned double SC's.
I used platinum upgrade on the MEL-PER leg, so can't tell if its the corporate traveller promotion or a stuff up at VA IT end that has changed things. Seems strange to not get double on outbound, but to receive on return - so I put it down to using an upgrade confusing VA, but that has never happened before. Plus the BNE-MEL leg remained in Y...
Getway fares are excluded from the promotion, which explains the outbound not crediting as double..
