It's certainly also a matter of getting used to it. Since Arch is a true rolling release and you update regularly, groups of common suspects, so to speak, are usually updated as well, i.e., packages that are dependent on each other. Replacements are even announced with a "replace" question. It certainly depends on what you have installed, but I find the listing in a row quite good, as it gives me a quick overview of a large number of packages without having to scroll.
Of course, it remains a matter of personal preference, but I just wanted to mention that Arch updates are somewhat different from release distribution updates, and some people (presumably, at least I do) appreciate seeing them listed in a row. To avoid accidentally overlooking certain updates, I have added some packages to the IgnorePkg list in pacman.conf so that they are displayed separately when an update is available. These packages include chaotic- aur/memtest86-efi, for example, as I have to mount the efi partition manually before the update anyway.
