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):

\catcode`\{=1
\catcode`\}=2
% ... and other settings (\hsize, ...)

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

\font\rm=cmr10
\rm
\hologo{XeTeX}

\font\lm=[lmroman10-regular]
\lm
\hologo{XeTeX}
...

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