ma'a as possessive: mass or individual?

--- and bless whoever puts these conundrums up!

How do you say "Each of us must bring their own toothbrush"?

Well, fascistically,

      ro da po'u ma'a bilga lenu bevri le denci lumci tutci po da

The question is, can this reduce to

      ro ma'a bilga lenu bevri le denci lumci tutci po ma'a

I think no, and that this sentence means "We all must bring *our*
toothbrush" --- i.e. the second ma'a in the sentence, like the first,
refers to a plurality of people, and (I construe) a mass, who all own the
thing in common. Adam thinks yes, and that the second ma'a behaves like da
("of each of us", rather than "of all of us".)

Is there anything anywhere that says one of these two interpretations is
incorrect? The Book gives me little light.
