Bug or feature?: PDF - display two pages in landscape mode

[Originally posted on the beta forum - did not receive a reply. I am posting here as it is not clear to me whether this is a feature or bug.]

Using DTTG 2.0 (15838).

On a iPad Pro 9.7 in landscape, when the full screen button is pressed:

after the first page of the pdf all the following pages are displayed 2 pages-to-view.

In portrait mode the following pages are displayed 1 page-to-view.

Is there a way to display pdfs when the full screen button is pressed 1 page-to-view by default?
