No it has! One can bind more than one language/script to a particular
feature and kern and liga are exactly such features. For example, here
are the binding for the font you are mentioning:
liga: DFLT{dflt} cyrl{dflt} grek{dflt} latn{AZE ,CRT ,DEU ,MOL ,ROM ,TRK ,dflt}
kern: DFLT{dflt} cyrl{dflt} grek{dflt} latn{AZE ,CRT ,DEU ,MOL ,ROM ,TRK ,dflt}
But a quick search reveals that no feature is defined for hebr{dflt}.
Nevertheless, if
the author of this font had defined
liga: DFLT{dflt} latn{dflt,AZE ,CRT ,DEU ,MOL ,ROM ,TRK } grek{dflt} cyrl{dflt}
hebr{dflt}
then obviously your examples would produce identical output. In different words,
if a font includes glyphs for the Armenian script and the Latin script and the
kern and liga features are defined for both scripts, then there is no reason to
use different fonts.
