Specifying the --output_name and then downloading 2+ files overwrites the first file

Just a matter of changing the file naming scheme when specifying the output dir along with the filename when using --output_name. Better to use --output_dir instead if you just want the multiple downloads to show up in the right output dir (moved at the end of all downloads).

Is this a bug?

Look at the CLI argument handling for --output_name and --output_dir in the main script. The bug likely occurs when multiple files are downloaded with --output_name specified; the naming scheme needs to be adjusted to avoid overwriting. Check how file paths are constructed and ensure each download gets a unique name. Test by running the script with multiple input files and the problematic flags.
