Ok, so when I said that exists() did not evaluate the variable, I was wrong. exists() is no different than strlen(), glob() or any other function. No matter the function, Vim always evaluates the variable before sending the result to the function. Usually this is what you want. But not with exists(), because usually you don't want to check whether the contents of a variable exists but whether the variable itself exists. So, the quotes are here to tell Vim: "don't evaluate the variable, leave it as it is".
