After reading this I thought Lou could stop worrying over being unreadable, but it seems the effect is not as omni-effective (there is a word for this, I know there is!) as believed.
UBC's Linguistics department shattered the dream:
"Anidroccg to crad cniyrrag lcitsiugnis planoissefors at an uemannd, utisreviny in Bsitirh Cibmuloa, and crartnoy to the duoibus cmials of the ueticnd rcraeseh, a slpmie, macinahcel ioisrevnn of ianretnl cretcarahs araepps sneiciffut to csufnoe the eadyrevy oekoolnr."
As demonstrated, a simple inversion of the internal characters results in a text which is relatively hard to decipher.
