It's true. However, there are few periodicals that can be expedited, and most of them cannot be expedited. I published an economic journal and just received an urgent page of 1 month, which was verified to be true. Later, I recommended my friend's article. His article is an educational article, which was published more than three months later when it was urgent. So it depends on the type of articles, not all of them can be published in 1-2 months.
