Are you assuming the person is reading your replies immediately after they are posted? When are these edits occurring? Hours later? Days later? Months later? Years later?
If the edits are within ~10 minutes to an hour of posting, I’d say it’s reasonably certain the person you replied to hasn’t even read them yet. So you can safely assume your edits will be read along with the original post.
Also, there is a 5 minute grace period after posting where edits to your post are considered the same as the original post, e.g. no revisions are recorded.
If you need absolute certainty that the person you are replying to has seen your reply, I suggest sending them a private message.
