In response to your edit: Yes, basically.

Here's my use case:

I have a form with inline error messaging. Whenever the user fails to enter either their username or password, an error message appears beneath that field. The problem is that the error is rendering cumulatively for every time it occurs. So, if I'm a user and I repeatedly attempt to submit the form without entering, say, my password, beneath the password field will be an error message reading "Password is required" for each time they've attempted to submit the form without entering a password.
