Whoa there.

That's the part which is your interpretation, and isn't in the rule
itself.

You're doing a logical transformation on the idea of "a set of stones
owned by a group of allies", making it into "a set of stones such that
there exists a group of allies such that each stone is owned by one of
the allies". But you can't do that with English sentences, and in
general in English we would consider it to be false that a set of stones
is owned by a certain group of allies if one member of that group owns
no stones in it.
