You're confused because you did not really read this post. Especially the part right before the image that says "follow luzcypher" that reads:

Remember, there is only one place on Steemit that it is alright to ask people to follow you but only if they really like your content and that is right here at the end of your post, not on someone else's.

Or the other part of the post that says it's OK to ask people to follow you on your own post but not in a comment on someone else's post.
