These arrows point in the upper-left direction for a reason: They signify that tapping them will take the suggested search terms and put them into the text input which is located in the url/tab bar above the arrow. At least that was the case until iOS 15, which famously changed that default. Now the direction of the arrows makes no sense. Apple used to care about things like that. This kind of seemingly insignificant detail is what made “it just works” a reality.
