Backlinks that you create are not authority backlinks.
Good points. I know what you're getting at. But that's a bit off topic to what the OP is asking.
The question to answer is, why does the backlink not show up in backlink reporting services? The answer is that it's a technical issue related to how often those services crawl the entire web and how often they refresh their data. It could also be a reflection of how complete their crawl is and what kinds of data they choose to report.
