When I checked, I found the following:

turtle.circle(50, 50)   # counter-clockwise
turtle.circle(-50, -50) # counter-clockwise
turtle.circle(-50, 50)  # clockwise
turtle.circle(50, -50)  # clockwise

So it seems both radius and extent need to be of the same signage to effect a counter-clockwise draw. However, for the 2 cases where extent is negative, the draw happens through the turtle's tail rather than the head. Looks weird.
