I'm not sure what you mean by "my action is on a working copy of something that points to a different repository." You can't merge between two repositories. The merge source is the repository, the merge destination is your local working copy, which was created from that same repository.

Not sure what you mean by "conflicts between those 2 source URLs". It doesn't make sense to talk about a conflict there. Maybe you're confused about the merge process in general? In which case, perhaps the Subversion manual (rather than the TortoiseSVN manual) would be a good place to start: http://svnbook.red-bean.com/nightly/en/svn.branchmerge.basicmerging.html

Merging can be though of taking a diff between two revisions of the repository as the "source" and applying that diff as a patch to your working copy. For a simple merge that you only need to specify one repository URL for, SVN takes a diff between rev X of that URL and rev Y of that URL and applies it to your working copy. For the merge that takes two repository URLs, SVN takes a diff between rev X of URL 1 and rev Y of URL2 and applies *that* to your working copy. But the two URLs are just used to generate a diff, so there's nothing that can conflict at that point.

http://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-dug-merge.html#tsvn-dug-merge-conflict-callback is what I was referring to, and it sounds like that's what you're talking about too. There is no "which repository"--there's only one repository.
