That is very true and I've always thought that was bunk. Primarily because that which is instinctual is survival. Such as mankinds ability to learn and adapt. While the skills we learn are not necessarily mandatory for us to survive on a basic level (and that's what survival really is), they do enhance our ability to survive by allowing us to surpass the limitations of animals.
Case in Point: An animal, which is very adept at surviving, such as a wolf, can learn to sniff out their prey. But this does not mean they have the tracking feat. This merely means they instinctively use their natural inborn qualities to sense their quarry or perhaps danger, mostly based on instinct honed by experience.
Tracking on the other hand uses more than just sensory perception, it also uses deductive reasoning, which is far more developed than an animal's basic instincts.
Case in Point: A wolf is tracking it's prey via it's ability to sniff things out. That prey, a man, loses it's wallet. A tracker would use the wallet, read the address on the ID or follow other potential clues that a mere animal could not possibly hope to comprehend. A wolf would simply keep following the scent, barely even registering that something was dropped, let alone what it's purpose is.
Case in Point: A tracker is following a wolf and doubles back over the river when the wold discovers him, breaking a branch or two along the way in his carelessness. The wolf will be unlikely to find him because a wolf using it's survival skill would completely overlook the branches. Tracking is more than basic survival.
I was always confused as to why WOTC lumped together tracking and survival. Tracking should be based on search, spot, and gather information. I guess they just chose simplicity over logic again.
