It is true. Apple has a 70% profit margin on sales that they reinvest.
Just because revenue is reinvested doesn't mean it isn't revenue or a margin.
And, seeing as Apple has >$100,000,000,000 of cash and near cash, your "reinvestment" line is a total fantasy. Apple is printing cash with a massive profit margin, and reinvesting a tiny tiny tiny fraction of that money back into their business.
