What you ask is impossible to answer. The reason: there are categories where the wait time for an editor review is in excess of three years -- and that assumes that all of the submission rules have been followed.
OK, so you got some bad advice. In all likelihood, it is not fatal. (I haven't looked, so I am speaking in generalities.) Sure, we have the right to stomp you for oversubmitting, but in practice, we don't often do that unless other factors come into play, such as mirrors, shotgun submissions all over the directory, etc.
So if you have been submitting the same URl to the same category, yor risk is minimal. Since new submissions overwrite older submissions, there is a chance that the reviewing editor will never know that you received and followed some bad advice. If the editor sorts submissions by submission date (some do, some don't) then your submission ill only show the most recent date.
I know ther are a lot of ifs and maybes here, but this is not a determanistic system that lends itself to predictions.
Unless you hve engaged in other forms of directory abuse, I would not lose any sleep over it.
