That would cause a frickin' riot in my session... supported by the rules or not, it states clearly in the text that that's what is does do.
That text, then, is wrong.
The original caster of the spell is still the same person. Thus, if someone casts a spell on me, and I turn it, it's as if he had instead cast the spell on himself.
Consider a spell which does 1d6 / level fire damage on a target. I (a 10th-level caster) am hit with this spell by a 14th level caster, but I have spell turning up, which completely affects the spell. How much damage does the spell do? 14d6.
Even better - I am hit by the same spell, but the spell is only 1/2 turned. According to spell turning:

For damaging spells, you and the caster each take a fraction of the damage.
Would you then suppose that the original caster takes .5 * 10d6 damage (1d6 * my CL), while I take .5*14d6 damage (1d6 * his CL)?
No, we each take a fraction of
the damage, meaning we each take .5 * 14d6.
About your other question:

Spells and spell-like effects targeted on you are turned back upon the original caster. The abjuration turns only spells that have you as a target. Effect and area spells are not affected.
SRD said:
Target or Targets: Some spells have a target or targets. You cast these spells on creatures or objects, as defined by the spell itself. You must be able to see or touch the target, and you must specifically choose that target. You do not have to select your target until you finish casting the spell.
Effect: Some spells create or summon things rather than affecting things that are already present.
You must designate the location where these things are to appear, either by seeing it or defining it. Range determines how far away an effect can appear, but if the effect is mobile it can move regardless of the spell’s range.
Ray: Some effects are rays. You aim a ray as if using a ranged weapon, though typically you make a ranged touch attack rather than a normal ranged attack.

Disintegrate is not a targeted spell, it is an effect spell. It creates a ray, which may be directed. This is an important, sometimes silly, distinction. Thus:
You said:
Well it's a range touch attack, you have to target someone to make an attack by the very nature of the word!
is not an issue.
