It could almost make sense actually, in that those things use quite high frequencies internally (100s MHz) and maybe they want you to stay away from it a little bit.... but much more likely yeah it's a typo, and that's precisely why it needs to be close up.
On that note, keep that in mind -- they can generate significant emissions, so a little filtering outside of that bypass cap (a ferrite bead and another cap, with everything laid out on ground plane) may be desirable.
