I'm not entirely sure it means anything and I'm not really sure the ebook is reliable. For one there are no line breaks -- it's just one big number. There are also two separate spans with the number (and the same zero width spaces) but the second is invisible alt text with occasional normal spaces.
Also, when I looked at it further the zero width spaces are sometimes in the middle of a word which is odd but it's still such a weird coincidence. Also, I would think that if any epigraph was going to be related that it would be the other Ceiling Rotation/Pattern epigraph.
