I'll explain - what does flash voting involve? An app.
Who is more likely to have this app - older or younger demographics? Some older adults will do and use it effectively but younger demographics are far more likely to have it and use it effectively. Also will anti-XF voters really download an XF app to vote? Thus we've already eliminated a bit of the older demographic vote and the anti-XF vote. Also if the app and voting is free, children and such can use it without hesitation from parents. Also it encourages the more active XF fandom to vote rather than the more passive casual viewer, to have the XF app in the first place (the 'am I bovered' sort of personality) or be bothered to vote in the first 10 minutes.
Thus when the first bottom 2 contestant is revealed with the flash vote, it'll reflect the targeted interested younger demographic's votes rather than the nation's on the whole. The second bottom 2 contestant which will be voted for based on the normal XF voting will be more representative of the whole nation not just the targeted XF population, so that will still be normal. But this way if you have loads of younger demographic (and some of the older demographic too) appealing acts and the odd mainly granny magnet (Eggnog, Maloney), then the granny magnet will definitely have a much greater chance of landing in the bottom 2 from the quick 10 minute first vote.
It was quite clever of the producers to introduce this actually. Especially if people forget to vote in a particular way (like last year when the producers tried getting people to vote straight after their fav act rather than waiting till the end and seeing all of them - this behaviour was soon forgotten after the novelty of the new voting system was introduced and people would vote at the end again like they always used to). So if they forget to vote/delay voting, then that first bottom 2 contestant will not be decided by their votes (they'll vote as how they normally vote - on Sunday morning or at the beginning of Sunday's show, not in the 10 minute interval).
