spell interpretation

i need help on the spell close wounds. what does it really do and how long does it last, and does it work past -10

[Biffoniacus_Furiou]

This spell cures 1d4 points of damage
+1 point per caster level (maximum
+5).
If you cast this spell immediately
after the subject takes damage, it
effectively prevents the damage. It
would keep alive someone who had just
dropped to –10 hit points, for example,
leaving the character at negative hit
points but stable.
The casting time is 1 immediate action, so you cast it right when an attack occurs. Its duration is instantaneous, so its effect happens right when it's cast and then it's over with.

If someone would receive damage, the healing of this spell is preventative rather than reactive. Normally, you would take damage and then your damage would be cured. With this spell, the healing granted instead prevents as much damage from happening. If a character is at 1 HP and he gets hit for 15 damage, which would drop him to -14 and dead, someone could cast this spell to prevent 1d4+5 of that damage from happening, leaving him in the negatives but never having gone below -10 and thus still alive.

It can be interpreted to prevent all of the damage, not just 1d4+5 of it. It's one of those "Useful under one, Worthless under another" cases.

"If you cast this spell immediately after the subject takes damage, it effectively prevents the damage [that would have been healed]." Thus it's still only 1d4+5 points of damage that it can prevent, not the entire attack.
