I’m quite confused with the difference between CLIPBOARD and PRIMARY
in X11 and in OS X. 

Evil calls `x-select-text’ in `evil-visual-{pre,post}-command’.

And here is the document of `x-select-text’:

x-select-text is an alias for ‘gui-select-text’ in ‘select.el’.

(x-select-text TEXT)

This function is obsolete since 25.1;
use ‘gui-select-text’ instead.

Select TEXT, a string, according to the window system.
if ‘select-enable-clipboard’ is non-nil, copy TEXT to the system’s clipboard.
If ‘select-enable-primary’ is non-nil, put TEXT in the primary selection.

MS-Windows does not have a "primary" selection.

So I set select-enable-clipboard to nil and now it works as expected —
`ox-clip' a region, when pasting in Libreoffice I get the formatted version,
when pasting in Emacs I get the original text.
