It is strange that this works. According to https://info.arxiv.org/help/submit_tex.html, \pdfoutput=1 needs to be in the first five (5) lines in the .tex file:

arXiv fully supports and automatically recognizes PDFLaTeX. You can ensure pdflatex processing by setting the flag \pdfoutput=1 within the first 5 lines of the preamble of the main .tex file. You should not need any other special flag.

Well, I called latex lni-paper-example.tex once with the lines in the class file, once without. pdfTeX switched to pdf output in the first case while it kept DVI mode in the second.

I guess arXiv's solution is meant for any kind of classes used. So a normal user has of course to add the lines to the tex file.
