Hi, could I ask a very short, at Fractal type fills how to change the fill handles asymetrically?

Basically I am trying Angelize's fractal tutorial from Xaraxone, and on the attached picture can be seen that the end fill handles are both pulled to the left. For me they are always in 90 degrees so maybe there is some keyboard short cut to pull them individually?
