In the way you imagine it, that is directly unpractical for reading, but 
practical for the one usage that I re-suggested initially: enabling a 
WYSIWYG text processor inside emacs.  You may want to visualize pages 
bigger than what fits on your screen, because it will be rendered on other, 
bigger screen, or unzoomed, or printed.

In a way you may not be imagining: both column contents could be 
unrelated, such as on stallman.org, and yet the most right column would be 
considered to be “after” the most left column, there, it wouldn’t be 
unpractical, because maybe you want to read only one column.
