Admittedly, this is getting into some strange corners of AsciiDoc, but you're missing the actual explanation in your disambiguation scenarios (though it's a mix of the first and last one). If the AsciiDoc processor encounters an orphaned block attribute line at the bottom of a document, it just ignores it. Likewise, if it finds one at the bottom of a delimited block, it also ignores it there too. In order words, if an orphaned block attribute line or block anchor is found at the bottom of a leaf (meaning no more content at that nesting level), those lines of metadata are simply ignored.
So what the processor is seeing inside the first example block is:
a
[example]
Try that in a document by itself and you'll see what happens.
In essence, you're correct that the bottom of a leaf (which you could think of as "before a block closing delimiter") is not a valid location for block metadata.
So Asciidoctor's output is correct in this case.
