They are not repatriating any money right now. Cook said in the interview they would be using funds that are already in the US.
“Apple boss Tim Cook has been criticized for missing a trick by carrying out a share buyback before the introduction of Donald Trump’s tax repatriation plan.
Apple posted quarterly earnings revenue of $52.9 billion Tuesday. The figure was just shy of expectations, but the firm appeased investors with an increased quarterly dividend of $0.63.
The firm also upped its buyback program by $35 billion and plans to spend a total of $210 billion buying back its stock by the end of March 2019.”

One billion to investment, 210 billion to stock repurchases.
As I said- unimpressive.
