Zooming in without reflow, makes things bigger, but means you now have to swipe to move the viewport over the text. It can be an annoying feature, though there are other things that can be annoying about actually reflowing the text as well, as a lot of the mobile layouts are already cramped, and as such zooming could cause other issues. It's a situation where you're given several really bad options, and you need to pick one you feel is most optimal. Locking the viewport to a specific zoom-level to prevent the side-to-side swiping is an accessibility issue, but makes the layout simpler.
