It's likely the authors used an existing conference template to fit in their paper's contents. Upon sending it to the conference, the editors can easily fit the contents in their prescribed format, and the authors know how many characters they can fit in the page limit.
arXiv typically contains pre-prints of papers. These may not have been peer-reviewed, and the contents may not reflect the actual "published" paper that was accepted (and/or corrected after peer review) to a conference or journal.
arXiv applies a watermark to the submitted PDF such that different versions are distinguishable on download.
