[css-writing-modes] elements that `text-combine-upright` applies

Currently the definition table `text-combine-upright` [1] says the property
applies to "non-replaced inline elements".

However, in Example 18 which explains the result of `text-combine-upright:
digits 2` applied to the fragment `<p>あれは10,000円ですよ！</p>`, the figure shows
that a span of characters ("10") are combined even the element applied is a
block element.

What does that mean? Is the example is wrong, the propdef is wrong (it
should say "non-replaced elements"), or neither (like the case of `digits`
it applies to block elements as well)?
