No, it just means that in autocracy everyone assumes institutions are corrupt, so no trust is broken. If you don't have trust, it cant be broken.

Perhaps ironically, there are still institutions that to some extent rely on social trust in autocracies. For example, black market is an institution. As is "bribe economy" – the general understanding that getting X done generally costs you around Y, where Y is not arbitrary. Then there's the whole thing about criminal organizations that typically rely on social cohesion and upholding all kinds of rules.
