I didn't vote, but my guess would be that it's because "aphantasia" (the inability to visualize images) is a popular topic on this site: https://en.wikipedia.org/wiki/Aphantasia. Some people see images in their head, and others (possibly overrepresented here) simply don't. My guess would be that a comment that starts by assuming everyone sees images in their heads was considered misleading and simplistic.
