It works as an implied apology, but you can also just say you're sorry and move on.

In my experience, both American colleagues, and older colleagues, tend to have a weird guilt complex that often prevents them from just saying sorry and moving on and not having it be a big deal. I think the god fearing, bible thumping, everything you do is a sin, kind of upbringing has knock on effects that lead to toxic behaviour like not being able to admit fault easily.

Imho, it shows far more confidence to be able to confidently admit fault and not be broken to pieces over it, you know that everyone makes mistakes and that you can fix yours better than most.
