My first reaction would be: This looks like a SEO hack "back in the 'ol days", where you would include relevant keywords with the same background color in your webpage :)

As others have commented, I guess it's a good idea to provide context of skills and competencies by describing your previous positions. Maybe a separate list for "skills" would be an option as well.

I came across some sites that required MS Word, which I still find weird, as extracting text from a PDF shouldn't be too hard as well.
