>Odds for 2 (1) below have increased (decreased) exponentially

Can someone help me parse this? Is it referring to #2 or #1 in the quoted tweet? Have the odds increased or decreased?

This is a common pattern in academic writing, which compresses two sentences into one, like so:

> In sunny (cloudy) weather, the sky looks blue (gray).

So the sentence above means that odds for scenario 2 have increased, while odds for scenario 1 have decreased.

Odds for option 2 have increased, odds for option 1 have decreased.

Increased for 2, decreased for 1.
