By what I gathered from all this years watching Naruto, Hand seal position DOES matter, but with enough practice and chakra control one can overcome this problem.

As for why do hand seal positions matter, think of a jutsu as a code if, for instances, you want to perform it you will have to "type" the exact "numbers", in the exact order to be a cast it.

Better yet, imagine that you have a pattern security code in your cellphone, and your pattern is this 9173, it goes from 9 to 1 to 7 to 3. Simple enough right. So you go and you try to do a different patter with the same numbers 9 to 1 to 3 to 7 (Here i swaped 7 and 3's position) it will create the same picture as your pattern but the order of your numbers are different so your phone will not unlock. So if you try to perform a jutsu with the wrong hand doing the seal needed you won't be able to do it.

This is what i think happens
