[csswg-drafts] [css-fonts-4] What does "italic values less than or equal to 0" mean in "Matching font styles"?

vlevantovsky has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-fonts-4] What does "italic values less than or equal to 0" mean in "Matching font styles"? ==
In "[Matching font styles](https://drafts.csswg.org/css-fonts-4/#font-style-matching)", in the section describing font style matching, step 4 is described as "If no match is found, italic values less than or equal to 0 are checked in descending order until a match is found".
According to the [OpenType spec](https://www.microsoft.com/typography/otspec/dvaraxistag_ital.htm), valid numeric range for 'ital' variation axis is defined as "Values must be in the range 0 to 1."

What does it mean when the CSS spec recommends searching for italic values less than or equal to zero, and what it is we expect to accomplish in this step?
