Multi-branch is for fitting more than one function & dataset with
identical parameters at the same time.
You just need to combine the files into one for fit, there are different
possibilities:
Do it permanently outside of gnuplot, or
fit f(x) '< cat data1 data2 data3' via ...
or
set table $data"
plot "data1", "data2", "data3"
unset table
fit f(x) $data
