I can't read your Word document (if you *must* create screenshots,
please post them to public webspace somewhere as .jpg or .png images),
but from the description you're tripping over the details of exactly how
a merge works.

First, a question: Can you reproduce the problem with the command-line

Second, a guess as to what you're doing wrong:

Instead of merging changes from r[n] to r[m] on the branch, to the
current trunk, you're merging the changes from r[n] of the branch to
r[m] of the trunk, into the trunk, so more or less by definition there
are no conflicts.

Put another way, the "from" and "to" revision/path specifiers are used
to create the diff, which is (usually) applied to the working copy in
the current directory. (With the command-line client, you can specify
an alternate directory path for the WC(-subpath) to operate on.)

Usually. <g> Tortoise hides some things, shows others in slightly
different ways, and isn't used by everyone on this list, so if it's
confusion due to how Tortoise shows or does things, you're likely to get
a faster, more accurate answer from that list.
