Because so far only V('V)* are variables.

See: http://xorban.wordpress.com/grammar/
Since a formula can end in "koi formula", "complement formula" also
can end in "koi formula". It's just that "koi formula" will be inside
the "formula" part, not added to the whole "complement formula" (that
would be ambiguous without a terminator).
A simple-formula is just: CCC* V(‘V)* ( k | f | b ) V(‘V)*
so for example "mlta" is a simple-formula, while "na mlta" is a
"complement formula".
so "jnva'akoi jnve'ekoi fgro'e" is unambiguously "jnva'akoi (jnve'ekoi
fgro'e)", there's no possibility of it being "(jnva'akoi jnve'e)-koi
fgro'e" because koi can only attach directly to a simple-formula, not
to a formula like "jnva'akoi jnve'e".
