Default Using lower accuracy schemes in boundary cells

I remember that I have read somewhere that when you are using schemes with high accuracy it is possible to use a scheme with lower accuracy(one order lower not more) in boundary CVs without losing accuracy in the whole domain. I'm not so sure and I don't remember where I read it so I can't just go back and check it.

I'm solving fluid flow / heat transfer in pipe using SIMPLE algorithm. QUICK scheme is implemented and UPWIND scheme is used at boundary. is this legit?
