It is proof for the tyranids having access to ork dna and yet they do not really seem to use it. the point being that orks have NOTHING to offer that the tyranids do not already possess, hence making the "tyranork" fanfiction pretty useless and eliminate the base of it. Only Hive Fleet Leviathan possess the slightest strain of Ork DNA, and are using to horrid effect (they're the most powerful Hive fleet in the galaxy at the moment). Let's take a look at how the Hive Fleets have evolved since then. Hive Fleet Behemoth was defeated by the Ultramarines and other Imperial PDF during the Battle of Macragge, which was a fairly small force, but now we have Leviathan which has rampaged a quarter of Imperial space and is facing what will soon be the largest concentration of Orks in the known history of the galaxy, since the waaagh is uniting them under Ghazghkull. Already the Hive Fleet is defeating these Orks, not only will they gain excessive amounts of biomass, but something in the Ork DNA (we can assume Ork DNA's reproduction methods or psychic traits is what draws them) is calling Leviathan and other Tyranids to take Ork DNA, as Tyranids tend to avoid biomass which can't be used or leave when opposition might be too much. Like said in the lore, (this passage comes from the Kryptmann article)

"''Kryptmann's plan seemingly worked, for Leviathan was diverted from its course to Terra, and both Orks and Tyranids were now thoroughly occupied with destroying each other, initiating the conflict known as the Octarius War. However, one thing is certain: each xenos race thrives on war, and there remains the possibility that if the Tyranids emerge victorious, the Imperium shall have to face a threat far greater than before, as in victory, Tyranids effectively lose no military strength or resources, their casualties and still living warrior strains reabsorbed by invading Hive Ships along with the remains of the conquered worlds, thus every victory has no repercussions, only benefits. This also means that the Tyranids will assimilate vast quantities of the strong, aggressive Orkoid DNA that makes the Orks such successful survivors and incorporate it into their own bio-constructs. Indeed, worlds on the edge of the conflict have begun to file with Imperial Segmentum Command pict captures of Tyranid assault  organisms that are larger and more formidable than ever before. Even though the Octarius War bought the Imperium invaluable time to muster and bolster its defences, the potential consequences of Kryptman's manipulation of this alien threat are too horrible to contemplate, and ultimately might prove disastrous in the long run''."

Callum and everyone else pretty much has the point down, if Tyranids gain hold of large quantities of Ork DNA, the galaxy is in deep trouble.
