2H2 + O2 yield 2H2O , so if i switch it around, 2H2O yield 2H2 + O2. Would it change which one is breaking bond, which one is making bond. So technically is the left side always breaking bond, right side is forming bond

yes that is true. think of decomposition of KCLO3 to give kcl and o2
Isn't that the way we write equations to show REACTANTS on the left and PRODUCTS on the right. So we usually are talking breaking bonds on the left and making bonds on the right.
