Pretty sure you are reading that incorrectly.
think of it as a head room limit associated with filesystem metadata.
For any filesystem of size X, where X is between (n)*16 Gb and
(n+1)*16 Gb where n is an a positive integer, the same amount of
headroom is avaliable for filesystem metadata. The online resize can
move the value of X only up to the (n+1)*16 Gb limit, no matter what X
actually is.  Anything beyond that boundary requires additional
metadata headroom which can only be added offline.

So a 14 Gig filesystem and a 15.5 Gig filesystem, can both only be
online resized upto 16 Gig.  Similarly a 23 and a 17 Gig filesystem
can only be brought up to 32Gig, which is the next 16 Gig increment.
