Oohh, I see. Neat.That's helpful already.
It still restricts the user to do inline-navigation, as opposed to the multiple tab workflow most users are used to. Is there a reason not to show the link in inline posts as well? The post anchor is useful inside threads, too.
I think it's down to cleanliness. I'm not sure id want links to the original post if I were quoting the post above mine. However I can see why you would if you were in a long topic of multiple pages (assuming pagination was activated), perhaps if the post you're quoting is > 25 posts away from the post you're making, it could link to the original, perhaps said: could be linked up with a quick link to the specific post. 0.5.1 should make finding posts in topics a lot easier with the new find feature.
