git-range-diff documentations says that the three-argument form:

    git range-diff <base> <rev1> <rev2>

is equivalent to passing two ranges:

    git range-diff <base>..<rev1> <base>..<rev2>

git-format-patch synopsis shows:

    git format-patch --range-diff=<previous> <rev-range>

where <rev-range> is the range of commits to format, and <previous>
can be a range specifying the previous version, so:

    git format-patch --range-diff=<base>..<rev1> <base>..<rev2>

should do what you ask.

However, since the two versions in your example both derive from
origin/master, you should be able to get by with the simpler:

    git format-patch --range-diff=<rev1> <base>..<rev2>

which, if you were running git-range-diff manually, would be the equivalent of:

    git range-diff <rev1>...<rev2>

for which the range-diff machinery figures out the common base
(origin/master) automatically.
