> a net cash neutral position over time

It's debt to cash-in hand ratio. Apple currently, as of March 2021, had US$120.2B of debt [1]. So, if they have $120.2B of cash, then it neutralizes their balance sheet. And, that's what the net cash neutral position is.

Edit - I missed adding liabilities. But, it will complicate the above terminology, a bit more. Although, I hope you got the idea.

This really should be the top comment under the OP's question. And Apple have stated this goal for a few years already. So this isn't new.
