With this configuration, the real document starts at section 3. To solve this, we need to add another section to contain all the mess, it means 2 more dummy pages: the first dummy page contains the section-break to odd page, the second dummy page contains just a normal page-break, and the third dummy page contains a section-break to next page. So printing from page 3 (which is page 1 of section 2) is messy because both are printed and other problems. The hidden page 2 is exactly the same as page 3.
When a first dummy page contains a section-break to odd pages, the page 2 disappears but is still there (just print the absolute pages 1-3 to see it).
