Is is technically not possible?

Due to our conversation about the RevisionGraph I understand that
revisions are repository wide, thanks for that enlightenment.
I already understood this when I wrote my last mail. Please accept that
I understand this now and see my questions not in the
impression, that I do not understand this fact.

So in this understanding let me ask a question. It is not a rhetorical
or offensive question:
There seems to be a difference in effect.
What is the difference in the repository at rev12 if I copy a tag from
trunk@10 or trunk@11?
In what aspect does the tag@12 look different?

Despite from the fact that revisions have to be seen repository wide:
The commit log feature of subversion distinguishes the path: you only
see the logs that are relevant to a path.
You do not see every revision log of the repository. And this is good,
else it would be too confusing.

And this is exactly the point. This is the information I want to see in
relation to trunk, but I see a log from a different branch if I hover
over the shown trunk@11.

Maybe you are right and it is a bad habit of me that I just use HEAD in
a copy of trunk to tag, even though the HEAD revision number was not
created by a commit to the trunk path.
But every tool in TortoiseSVN seems to respect this.

Let me turn it the other side round:
How can I bring the graph to a state, that I would like to see?
Do I have to set the copy to a specific revision number (e.g. the rev.
number that was created with the last commit to the trunk path)?
So wouldn't it be nice to have a shortcut in the copy panel for:
"Take the revision number of the last commit for the 'from:" path"

Thanks again for your ideas and the conversation.
