using "svn merge", "svn diff", and "svn patch"

Not sure if this is a valid operation, but should I be able to use svn
merge, then svn diff to create a patch, then svn patch on another branch
(or pristine checkout of the originating branch where the diff was created)
to create a replica of the merge operation?

The reason I ask is that it appears not to do that.. I get an "Skipped
missing target" error on one file that was added with history with the
merge, another in the same path that doesn't error or add, and apparently
no mergeinfo included at all.

I can't really share what I've seen since even the file names are
considered proprietary, but I may be able to write a script to reproduce.

Has this been seen or just not an acceptable use-case?
