Wednesday marks the start of the oricon week, so only naturally one would want to have as much time as possible for sales to occur before the weeklie sales ranking is given. Basically it gives the single the maximum amount of time to sell before the weeklies rank is given...
Also this double sided single "strategy" might just be because either Ayu likes that style, she produced so many single worthy songs this year or that fact that her single-song singles started to suffer after moments and carols.
