Unless you are using iniTeX it's probably a bug. In the latest
version I can't reproduce it, however the latest version isn't
yet on CTAN. I send it off-list to you, thus you can even
use it with iniTeX (xetex --ini):

% ... and other settings (\hsize, ...)

% Since 2011/12/21 v1.9
\input hologo.sty



The logo uses U+018E if the font has this glyph otherwise
the reversed E is constructed.
