Restriction on svnmucc targets in same repository?

Is there any restriction on svnmucc targets which can appear in a batch script?

I assume that all targets must be in the same repository, but are
there any further restrictions, e.g. must they have the same initial
root directory path?

I ask this because I am getting the following:

svnmucc: E175013: Access to '/.../!svn/rvr/98024' forbidden

The script is equivalent to:

put
file.txt
top1/file.txt

mv
top2/d1/file2.txt
top2/d2/file2.txt

top1 and top2 are different top-level root folders in the same repository, i.e.
svn info root/top1 gives the same UUID as svn info root/top2
