If the site merges some consecutive edits …
Edits aren't merged, really. Consecutive edits within a window of five minutes after the last edit (or first revision) are just shown as the last one.
… will I and my reviewers see the merges the same way?
Yes, there is really no difference between how the author of an edit and other users see it. The only exception is the actual preview of a post. When you submit an edit, the post will have a banner telling you that the edit waits for approval, while other users still see the original revision.
