to give the fuel/air more time to mix better at higher revs??

yes allows better atomisation for top end power

yes, it allows the fuel and air to travel further therefore better atomisation (better mix)
downside is that when you shut the throttle, the injectors spray fuel at the throttle plate (butterfly) and it will stall. Unless its a race spec car that isles stupidly high or has 4 lower injectors and the upper cut in at higher revs, its pointless.

There is a lot of fluid mechanics / maths to work out exactly where they need to be put though... There is always an optimum spot for them to sit for the required ammount of power and revs you are using.
