M&M 3e how does indirect modifier work?

[Tanarii]

Indirect 1 seems simple enough, choose a point that's not you, and the effect always originates there and goes directly away from you. Probably want it still somewhat near you, unless you want a huge blind spot where you can't hit someone. But still useful for shooting from behind a wall or something. Or just being thematic to the descriptor.

Indirect 2 has two options.
Option 1 is simple, any time you use the power, chose an original point that's not you, and it goes directly away from you. Simple enough, that's basically a flexible Indirect 1 starting point.
Option 2 starts at a specific point that never changes, but doesn't have to go away from you. That sounds like a flexible Indirect 1 direction of fire. But the example given are a bolt of lightning that arcs up and then back down, and a pillar of fire that goes up. Given the first example, does this second option allow you to fire in non-straight lines, or is it always from the non-flexible point of origin in any straight line?

Indirect 3 "can come from any point in a certain direction (like calling lightning down from the sky)" Wait, what? Does that mean it's Indirect 2 option 2, except the origin point is flexible in distance from you, but not relative position? And the direction of fire can be any (but possibly bending as opposed to a straight line)?

The most coherent reading I’m getting is that “away from you” refers to the direction the ranged effect travels in.

Indirect 1: the beam projects from a point in space 6ft in front of you, traveling directly away from you

Indirect 2: beam origin arbitrary along a line but beam must shoot away from you, or predefined beam origin with a 180deg arc that ?opens away from you?

Indirect 3: arbitrary origin point along a line with 180 arc ?away from self? or set origin with no aiming limitations

Indirect 4: full free aim
