No, the above should be working. You say that the OSM files are
custom made. Did you make sure that both files use different OSM ids?
Otherwise, the second file will be considered an update of the first
file and then the second file will indeed overwrite the first.

I strongly recommend to merge the files first and then import them into
Nominatim in one go. This is always faster than using the update function.
You can also then check if the size of the combined file this way and
check if that makes sense before the lengthly import.

Kind regards
