If you start rolling the die the first day that you want to lie yes then it is very suspicous and doesn’t really gain any concealment benefits. But starting to roll the die gives the option to lie. And in the flipside it forfeits that your word is worth that much. Even if you never actually lie people can’t take your word so seriously.
If you just claim to roll but never actually roll that is a very different case.
