Because quantifier ordering counts.  The persons have to be mentioned before
the heads are.

1)	ro remna cu ponse pa stedu

is equivalent to the full prenexed form:

2)	ro da poi remna pa de poi stedu zo'u da ponse de
	For all X's that are human, there is one Y that is a head, such that X owns Y.

So Example 1 and Example 2 are true.  Whereas if you said

3)	pa de poi stedu ro da poi remna zo'u da ponse de
	There is one Y that is a head, for all X's that are human, such that X owns Y.

it would be false, for we don't all have the same head.  If you get the
quantifiers in the correct order in the prenex, then you can
use any order you like in the main bridi; otherwise, the order in the
bridi is presumed to be the order in the prenex.

Those both work, and indeed better, for "ponse" is not truly appropriate.
We don't *own* our heads (and carry them about in our briefcases!); we
*have* heads.

> {[some other prosumti] stedu ro remna}?

IMHO the best (certainly the shortest) way to say what you want is:

4)	ro remna cu se stedu pa da
	Each person is-headed-by one something

which in full prenex form is:

5)	ro de poi remna pa da zo'u da stedu de
	For all Y's that are human, there is one X, such that X is the head of Y.

I don't think this works either:  "Look! A head of every man!"
