Visiting Macao under Hong Kong visa-free policy

Hello, I'm Ukrainian. My itinerary is Ukraine - Beijing ( free-visa transit 144 hours) - Hong Kong (3 days )- ship to Macao ( 2 days ) - back by ship to Hong Kong and air out to Ukraine from Hong Kong.

Is it valid? Can I visit Macao for few days from Hong Kong? Because according to the Hong Kong policy:

where the application is for a transit visa/permit, he/she holds an onward ticket to the place of his/her destination unless the destination is the Mainland of China (the Mainland) or the Macao Special Administrative Region (SAR).
