I just tried doing this, and it looks like the R-free flags will cover
the full resolution range, at least with the current code. You can
verify this by running phenix.mtx.dump on the output MTZ file, or in
the GUI, click the magnifying glass icon next to the file name and it
will pop up an info panel.

That shouldn't matter, as long as you told it to take lattice symmetry
into account when creating the flags (use_lattice_symmetry=True, which
is the default - I'm not sure why this is even optional).
