Scirocco Central

I saw the bestmotoring video in which the Scirocco R is the first to arrive at the finish line, winning on Golf R and Lancer Evo, ecc. ecc. I saw that in the hard braking the red rear lights of the Scirocco R flash intermittently. This function is only for the japanise version? I remember that my old astra gtc had the same funcion.
Thanks for the answers

This maybe a stupid statement, but I know some Jap cars don't have "amber" rear indicators but red ones instead - was it the indicators, because they do flash under heavy breaking.
