I think their point is not that the resolution of human data is lower (although I expect it is quite a bit lower than 44k Hz). Instead, I think they are pointing out that fewer data points are necessary. If your jazz drummer plays eight notes in a second, the timing alone can be represented in eight floating point numbers (a higher resolution than CD audio); the data is 8 * 8 bytes -- much smaller than the 44k * 4 bytes of raw audio samples that would be needed for a second of stereo CD audio. (I realize a drummer's performance encompasses several other variables, but these data points are similarly sparse relative to CD audio.)
