I suspect the history of your tree is just more complicated than you
are alluding to. To answer your final question, no that is not true.
The mergeinfo should not contain information for the "natural history"
of the branch. Put it this way, suppose this project had began its
life after SVN 1.5 had been released. Would the current mergeinfo
contain references going back to r1? The answer is no, it would not.

Here is an easy test you can do:

svn copy -r336 -m "Create branch to test merge"
url://server/repos/trunk url://server/repos/branches/merge-test
svn co url://server/repos/branches/merge-test merge-test-wc
cd merge-test-wc
svn merge url://server/repos/trunk
svn pg svn:mergeinfo .

The mergeinfo that is created is the mergeinfo you should now have on
your other branch as well. This test basically creates a new branch
from r336 then immediately does a merge of all changes it does not
have.
