Re: prefix hijack by ASN 8997

I received a phas notification about this today as well...

I couldn't find any relevant data confirming the announcement of one
of my /19 blocks, until a few minutes ago when i checked the route
views bgplay (ripe bgplay turns up nothing) and can now see 8997
announcing and quickly withdrawing my prefix

I am hoping to confirm a short-duration prefix hijack of 72.234.0.0/15 (and another of our prefixes) by ASN 8997 
("OJSC North-West Telecom" in Russia) in using ASN 3267 (Russian Federal University Network) to advertise our space 
to ASN 3277 (Regional University and Scientific Network (RUSNet) of North-Western and Saint-Petersburg Area of 
Russia).

Is that what I'm seeing when I go to "bgplay.routeviews.org/bgplay", put in prefix 72.234.0.0/15 and select the dates:

22/9/2008  9:00:00   and   22/9/2008  15:00:00

If so, am I understanding it correctly if I say ASN 3267 saw a shorter path from ASN 8997, so refused the proper 
announcement from ASN 36149 (me) it normally hears from ASN 174 (Cogent).

If the above two are correct, would it be correct to say only the downstream customers of ASN 3267 were affected?
