That depends. For example, if you have 2 monsters, you attack with monster A twice using Double Attack, monster B once and the opponent uses Phase Seal Chain, then you use this. Monster A won't regain Double Attack cause it's once per turn and this just gives an additional attack phase. If you didn't use Double Attack or effects like it, then yes you can.
