No, of course not.  Only the minimum amount of hscroll will be the
same for all the lines.

If auto-hscroll-mode is set to current-line, then typing "C-u 5 C-x <"
will hscroll all lines by 5 columns.  If you then move cursor so that
it gets too close to the right margin of the window, the current line,
and only that line, will be hscrolled by more than 5 columns, in order
to bring point into view.  The other lines will remain at their
5-column hscroll.

IOW, in this mode "C-x <" affects all lines, but only the current line
is scrolled more than that when needed.
