First-class investigation, sir! Well done.
Yes, ABE is oriented around the destination of the request. If you examine its history, you'll find that it was originally intended to protect against Cross-Site Request Forgery. 'Site example.com' was meant to indicate "a set of rules to describe how other sites are allowed to interact with the sensitive site example.com."
ABE can be a general-purpose content blocker, and it's a very powerful tool for the job. However, the lack of a graphical interface, and especially the lack of obvious feedback about what is blocked (it's on the Messages tab of the Error Console), make it difficult to use for this purpose. Unless you're really keen, then RequestPolicy is probably plenty. It doesn't quite have the fine-grained power of ABE rules (regular expressions, distinguishing GET from POST, anonymizing requests, etc), but it's easy to use and gives protection far beyond what most people have.
However, Flashblock is redundant. Just go to Options-Embeddings and enable 'Apply these restrictions to whitelisted sites too'.
