^Do reread chapter 430 she released her seal and transfered all her chakra to Katsuyu in order to save village from Shinra Tensei. Moreove it does not matter what you think as long as facts speaks otherwise. There is no mark on forhead. But whe she wokes up it already there and then she begins to eat in order to maintain chakra. So time for Tsunade to reform the seal from week if it began rebuild it self while she was in come(impossible from Sakura explanation) or few hours since moment she woke. And we know how much it takes for Sakura to form seal - 3 year if Sakura releases seal and uses all chakra in it she will need another 3 years(may be less since she adult right now but not that much) to form it again. Considering chronology wise first person(know to us) to bear this seal was Mito Uzumaki - wich speaks why this seal is hard for Sakura - cause it was invented by clan who never bothered by having low chakra reserves - unlike fodder origin Sakura. So yeah without solid plot reason from Kishi - Tsunade owns Sakura anytime anywhere.
