I feel obligated to first say that despite my reputation and some people's opinion to the contrary, I am not the arbiter of rules and am not an official response. This is merely my personal opinion.
I think the card text is not clear. The use of the pronoun and what it is referencing when the source of the spell is suddenly changed can be argued, and trying to argue it is not going to get us anywhere. I prefer Puddnhead's method in this case, looking at the intent.
Option A: Force Pull always pushes towards the Forcemaster. Nearly every situation under this option will end up working exactly how Force Pull has always worked, and was clearly intended to work. The only exceptions are if you target the Mage herself or any other creature in the same zone as her. In which case the two possible interpretations are that nothing happens, or that she may push the creature in any direction. I'm of the belief that nothing would happen. The reason for this is clearer when talking about other creatures in the zone with her, as pushing them out of the zone obviously doesn't follow the rules of the spell. They'd be moving further away, not nearer. The same is true when used on the Mage though. You are moving her away from her current location, not towards it. So basically, Option A uses the Mind's Eye to increase range but does not affect functionality.
Option B: Force Pull pushes towards the source, i.e. the Mind's Eye. This would be consistent with the rules for Pushes in general. Their direction is generally in reference to the source, not the caster. However, this grants Force Pull all sorts of new functionality, in addition to increased range. Obviously it now lets you pull things AWAY from the Forcemaster, which is the exact opposite of what it was originally supposed to do, and makes it much easier for the Mage to disengage and keep things a safe distance away. It also allows you to pull yourself, giving you increased mobility. I don't think there's any way to argue that this isn't as intended for Force Pull. But maybe it's the intent for Mind's Eye? Puddnhead references Reverse Magic and Reverse Attack, but that seems like a poor comparison to me. The effect of those spells isn't really changed. They've always targeted the source, and have had rulings on that going back to the core set and Chain Lightning. And casting them out of Mind's Eye doesn't change anything about them. The only thing happening there is the fact that Mind's Eye can trigger them.
Jet Stream is a better example. But here I think it's important to realize that this, and any other example you can come up with, aren't Mage Abilities. Any spell card you can point to as an example has the property of being a spell card, and thus designed with the idea in mind that it may be cast by a Familiar instead of by your Mage (Note, I recognize that Magecast spells exist, but I couldn't find any relevant to the discussion). That's not the case with Force Pull. It's initial design and intention was always that it would be pushing things towards the Mage.
That's why I think Option A is the right interpretation. It pushes them towards the Forcemaster, and if you target the Forcemaster herself or any other creature in her zone, it doesn't do anything. Not because it has the best argument grammatically with regards to the pronoun, but because it preserves game play and avoids unintentional uses of an ability.
