I think it does, in that it's doubtful they'd have offered this unless they thought they were in a much stronger position where a far smaller number would have considered it enough to decide to leave.

You don't do something you expect to lead to a third of your company leaving. Even if you were actively planning a round of redundancies, you wouldn't do this as you risk losing your best performers.

The cost they'll face in fixing this loss of company knowledge, hiring and training replacements will be several times the cost of just the severance.

Noblesse oblige.
