It shouldn't be spraying there by design, but it's not a bad thing in this case.

I don't necessarily disagree...but I'm a freak when it comes to water leaks - absolutely cannot tolerate them. On a yearly average I'm broadcasting 25,000 gallons a month. I don't want to spend one cent more than what's needed to care for the grass. Yes, you'll never see my yard getting irrigated during a rain nor will you see any runoff going down the gutter!
That's a great observation about the grass between the nozzle and wall - and there are many of those in my landscape - but none of the "back" grass ever browns. I believe that's attributed to there being enough "close by" water saturation that the roots are picking up on it. Also, what you don't see is there are other heads down the line that overlap the leaker. That pretty much covers the back grass too.
