Each OpenType feature has to be bound to a specific set of scripts/languages,
this has nothing to do with the "Script/language sensitivity" hint in the
pages you are pointing to.

Try:

\documentclass{minimal}
\usepackage{fontspec}
\begin{document}
{\fontspec[Script=Hebrew]{Linux Libertine O} fi fl ffi ffl AVAW}\par
{\fontspec[Script=Latin] {Linux Libertine O} fi fl ffi ffl AVAW}\par
\end{document}
