Depends.

Currently, Emacs supports right-to-left scripts. It provides a set of
commands that move the point in logical order
({forward|backward}-{char|word|symbol|line|sentence|paragraph|page})
and a separate set of commands that move in visual order
({left|right}-{char|word}, {previous|next}-line).

Let’s assume Emacs will advance to be able to display multicolumn
layouts while keeping these concepts of logical and visual order
separate.

Assuming best current practices for HTML, the main column precedes the
sidebar in the document order. Therefore, M-< moves to the T in “This
is the page content”. Then, “forward-sentence” moves the point after
the period. After that, you set the mark and use “forward-sentence” to
move point after “whatsoever.”. Now “copy-region-as-kill” puts the
sentence on the kill ring.

At the same time, moving with arrow keys would give the user intuitive
visual-order movement, where pressing <left> while the point is before
E in “Emacs may apply” moves the point all the way forward to after
“left of the”.
