On reflection this text (which was also in CSS Fonts 3) is too brief:

> When kerning is enabled, the OpenType kern feature is enabled (for vertical text runs the vkrn feature is enabled instead).

how about

> When kerning is enabled, the relevant  OpenType kerning features are enabled (for upright,horizontally set characters and for rotated, vertically set characters, the `kern` feature; for upright, vertically set characters, the `vkrn` feature. ).

followed by three examples - one of horizontally set text, one of vertically set text with all characters upright, and one of vertically set text with some characters rotated. I'm imagining color-coded backgrounds behind each glyph, for `kern` and `vkern`. That would also show (which should be obvious, but still) that a change between upright and rotated breaks kerning.
