I just don't see how not reimplementing from scratch for Mac can be used as a negative point.

Easy: if you have sensible format then you don't need full windows importer to port it. You can grab separate already-written pieces (MathML, PNG, SVG, etc), write glue code from scratch - and get full importer.

KWord does not use ODF-importer from OOo, for example. Even if both OOo and KWord use libpng to import png images.

But when your format is so complex and when its parts are so intertwined that you only have all-or-nothing choice - then yes, the only sensible way is to port existing importer...

I'n not saying that MacWord team did bad - I'm saying that if what they did is good... then OpenXML must be pretty awful for it to be good decision.

Why would they even write the glue code from scratch? As the blog posting points out "There is a lot of commonality between the in-memory data model for Win32 Office and Mac Office, since they share a lot of the same code". Writing from scratch should be the last resort. That would be like Win-OpenOffice and Linux-OpenOffice having independent code for importing the same documents.

The comparison between KWord and OOo is bogus. They don't come from the same codebase to start with so there would be very little that they could reuse. Let's imagine they somehow did share the ODF importer code, would that imply that ODF was so horrible and complex the the KWord team had to reuse the OOO code?

I haven't read the spec for OpenXML but I believe everyone when they say it stinks. There are apparently lots of reasons. That MS are resusing code between Win-Word to Mac-Word is not one of them.
