The two aren't connected. They announced 10% layoffs in January and executed it. Then they announced that they would be rolling out stack ranking and PIP quotas for managers, but both of those decisions were later reversed (https://www.businessinsider.com/salesforce-plans-ranking-emp...).
It's actually unclear as to whether or not they have done all of the layoffs. From your article:
> The company has been reducing its workforce since November, when it cut hundreds of salespeople. In January, the company announced restructuring plans to lay off 10% of staff — roughly 7,000 people — and shed some of its office real estate.
> Since then, thousands of workers from that planned 10% cut have been notified of their terminations. Insider has also reported that remaining employees are feeling increased performance pressure, and some are being pressured to quit with severance offers that are not as big as those being laid off.
> Salesforce has not confirmed whether it has notified all 10% of workers included in the official restructuring plan yet. Insider previously reported that at least one person familiar with the matter said the company was evaluating last month whether it needs to cut an additional 10%.
