style:writing-mode attribute (on elements sections) - confused wording

The text: "The defined value of style:writing-mode attribute is page: writing mode is inherited from the page that contains the element where this attribute appears."

Appears on <style:graphic-properties>, <style:page-layout-properties>, <style:paragraph-properties>, <style:section-properties>, <style:table-cell-properties>, <style:table-properties>.

It could mean:

1) the value of style:writing-mode is always inherited from <style:page-layout-properties> for the page where the element appears. (unlikely)

2) the value of style:writing-mode can be set for each element, and in the absence of the attribute and/or a value, then its value is inherited from <style:page-layout-properties>.

If the latter, suggest:

If the <element-name> has no style:writing-mode attribute or if the value of the style:writing-mode attribute is the empty string, then it inherits the style:writing-mode attribute and its value from the page where the element appears.
