I see how you see.

How I described, is similar to how spreadsheet program reacts.  It
lets user scroll both by <wheel-left> and <left>.

I very often edit a buffer with long and short line (for example,
LaTeX table), using mouse and keyboard.  However, as you infer, this
can be already very special.

Isn't my description convincing enough to install the line that
invokes the minor mode `touchpad-disable--auto-hscroll-mode'?
