Alla:

I don't think that necessarily points to anything for the simple 
reason that Levicorpus was also found in the same six year book and we 
KNOW that it was invented earlier than that.

I think same thing can easily happen with Sectusemptra.

Alla:

I will take a bite speculating what cause Snape may had to invent
truly Dark curse before Prank ever happened. Could it be that Snape
was always attracted to Dark deadly curses, could it be that he
indeed knew many Dark curses when he arrived at school?

Could it be that Snape interest in Dark magic is what drew him to
Voldemort? Oh, yes and with every book I see more and more support
for that.

After all, Sirius just could not have been right in anything Snape
related matters, even if he simply delivers facts, and Snape had
nothing to do with dark curses whatsover, except of course we know
now that he did.

I think it could be so. I think Snape inventing Dark curses WAS one
of the reasons of his rivalry with James, who always hated Dark
Arts, but after all I believe that Snape had always had very Dark
nature.

Alla, speculating here, but happy that HBP did not disillusion her
speculation, on the contrary.
