If thats not the intent of the feat then what is the intended purpose of it?
Well, first of all, it is an example feat only, that's why it's in that sidebar and not in the feat section. Then, the author of the feat himself has said (on the WotC forums IIRC), that that is NOT the intent and the feat should not do this (allow for prerequisites); it was an oversight, that the wording technically allows this (with some vagueness; it was said there, that the feat does not really grant the ability to cast 2nd-level spells, since it has a chance for failure, so it's a step below that ability still).
Why is this not the intent? Because it is completely broken, that's why.
Build some MT characters, that abuse this feat for a prerequisite, and you will quickly see this.
So, this leaves the question, what the intent of the feat actually is...
It grants you a bonus 2nd-level slot (it's similar to Extra Slot in that way), and the ability to use it (within limits) even before you have technical access to 2nd-level spells. That's the intent. And that's what the feat does and should (only) do.
