Does severance package get reduced in subsequent rounds of layoffs?

This is the kind of niche information that I can't really find anything on Google for. :/

I imagine the layoff package will remain around the same, especially with these large profitable companies that have mountains of cash and are able to foot the bill. Here's why:

• Brand is important - Having an ultra-competitive layoff package maintains image and minimizes the damage to ability to attract talent.
• Minimize pushback - If future packages are substantially worse, a lot of the more recent laid off folks will complain and potentially pursue legal action.
• Keeps the door open - Of course, an employee won't be happy after getting laid-off, but if you want a chance of potentially hiring back that person, a strong severance package is the first step. This is especially true for FAANG companies that are so good at hiring great people - Reclaiming the talent they lost once economic conditions improve is a solid option.

Again, this is entirely guesswork, so take it with a grain of salt. If anybody has more information and experience with this, please correct me!

For what it's worth, I looked up Coinbase's layoffs (Coinbase is a company I consider at the level of FAANG), and it seems like the packages were comparable for the 2 layoffs they did in the past year. Robinhood, a similar company, did the same.

Lastly, I recommend these resources:
