Nope, seems clear enough to me and doesn't impact me, mainly because I don't have an account with them! 
They reckon that 99.8% of their customers will be on the standard commission rate of 2% of net profit in each market so totally unaffected by this. The remaining 0.2% will be mainly high volume traders. Anyone looking to trade in that style will just have to factor that commission basis into their calculations before deciding whether a given trade is worth it or not.
