This particular example isn't actually money laundering.
However, in general yes - a 30% haircut on laundered money isn't too bad at all. Consider the classic money laundering scheme: you own a legitimate bar, but supplement the real sales with ghost sales, paid for by the dirty cash. The alcohol supposedly sold in the ghost sales is poured down the drain, so your suppliers invoices match up with your sales (this works because it's typical for customers at bars to pay in cash, and the margin on alcohol sold as individual drinks is pretty high).
