No.
Let me give another example of the problem.
If you go to https://yoast.com/cat/analytics,seo/page/41/, this link contain the posts of all post that have analytics and/or seo as the category.
If you view the source, it’ll display the canonical as,
<link rel="canonical" href="https://yoast.com/cat/analytics/page/41/" />
which is wrong, because that page doesn’t exist, which lead to an 404 crawler error in google webmaster console.
The correct should be:
<link rel="canonical" href="https://yoast.com/cat/analytics,seo/page/41/" />
The same error is prevalent in multiple tags.
