Comments are meant to be for short temporary discussion, clarifications, or to add relevant but minor/transient information to the post (such as links to related questions).
The comments on that question were removed by a moderator because they weren't needed to stick around over the long-term. Especially considering that an answer was posted, which pretty much covered the "jump and run around" point you made.
Note that comment removal isn't a 'bad mark' against you or anything, just a regular cleanup process of the site, which regular users can do too by flagging comments. 'It's no longer needed' is a direct reason one can pick:
What are comments?
Comments are temporary "Post-It" notes left on a question or answer. They can be up-voted (but not down-voted) and flagged, but do not generate reputation. There's no revision history, and when they are deleted they're gone for good.
