Greater Dispelling vs. Spell Turning

[Dark Dragon]

Spell Turning is a quite effective protection for a wizard against Greater Dispelling. But can ST protect itself against Dispel Magic and similar effects?

SRD:
Spell Turning
Abjuration
Level: Luck 7, Magic 7, Sor/Wiz 7
Components: V, S, M/DF
Casting Time: 1 standard action
Range: Personal
Target: You
Duration: Until expended or 10 min./level
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. Spell turning also fails to stop touch range spells.
From seven to ten (1d4+6) spell levels are affected by the turning. The exact number is rolled secretly.

Dispel Magic
Abjuration
Level: Brd 3, Clr 3, Drd 4, Magic 3, Pal 3, Sor/Wiz 3
Components: V, S
Casting Time: 1 standard action
Range: Medium (100 ft. + 10 ft./level)
Target or Area: One spellcaster, creature, or object; or 20-ft.-radius burst
Duration: Instantaneous
Saving Throw: None
Spell Resistance: No
You can use dispel magic to end ongoing spells that have been cast on a creature or object, to temporarily suppress the magical abilities of a magic item, to end ongoing spells (or at least their effects) within an area, or to counter another spellcaster’s spell. A dispelled spell ends as if its duration had expired. Some spells, as detailed in their descriptions, can’t be defeated by dispel magic. Dispel magic can dispel (but not counter) spell-like effects just as it does spells.
Note: The effect of a spell with an instantaneous duration can’t be dispelled, because the magical effect is already over before the dispel magic can take effect.
You choose to use dispel magic in one of three ways: a targeted dispel, an area dispel, or a counterspell:
Targeted Dispel: One object, creature, or spell is the target of the dispel magic spell. You make a dispel check (1d20 + your caster level, maximum +10) against the spell or against each ongoing spell currently in effect on the object or creature. The DC for this dispel check is 11 + the spell’s caster level. If you succeed on a particular check, that spell is dispelled; if you fail, that spell remains in effect.
If you target an object or creature that is the effect of an ongoing spell (such as a monster summoned by monster summoning), you make a dispel check to end the spell that conjured the object or creature.
[...]

Since ST turns only spells targeted on the caster, it shouldn't turn Greater Dispelling directed at ST, because the spell is targeted, not the wizard with ST.

Of course, this tactic would only make sense when the dispelling caster knows that his opponent has ST cast.

What do you think?

Somewhat ambiguous. Since GD specifies "Target: One spellcaster, creature, or object; or 20-ft.-radius burst", it may be interpreted that targeting a spell on an object or creature is the same as targeting the creature or object. ST would kick in.

There is no such ambiguity with the area form of GD, however.
