This is still a rich topic with many permutations.

The screw seems to be a bit short on the left.
The screw/cylinder can be length extended to the left.
The helix and reverse helix can be copied to the left, and FLIP applied to reverse start point.
The bottle can be arrayed to the left, with a negative rotation of -90 degrees...

(If Unflipped, array to the left created an expanding conical-ish spiral...)

I have yet to grasp the reverse screw. The script will work if ...
