Not that strange, Cervelo had a 2-position seatpost on the pre-2013 P2/P3 (the current ones have a long v-way to achieve the same thing), some other TT/tri bikes had reversible seat posts to give a similar effect.
But at least they can move it to the rear position and make it look better, an opportunity not afforded by some of the tri bikes which fell foul of the fashion for steep seat angles 😀
