This is saying that she only gains increased MS while her Atk Spd buff is active. Each stack increases her MS but duration of the MS buff is always 3 secondsSo

if you atk or Lunge during the last tick of her Atk Spd buff...aka at the end of the 3 sec of her Atk Spd buff... her MS buff will be refreshed and she'll gain 3 more seconds of increased MS for a max total of 6 seconds of increased MS.
