That's clearly not what was meant, even without the context of this following bit:

To describe tones that exist in music, we can describe tones that exist on a piano. There are only two rules:

the first key must play a tone of 27.5 Hz each next key must play a tone 6% higher than the previous key

(This is not to mention that at a 1.06x increase per half step you're going to be sharp by 1 cent / octave which starts to add up).
