No, it does not contradict what I said if you look at it with precision. The text is from around 30 to 40 AD. The Barbaroi clothing is similar to what they wore in Egypt and in other Greco-Roman places because Cushites wore clothes that were similar to ancient Greek and Romans. Pay attention to how the commas separate. Our historic common clothing is similar to what they would wear in Greco-Roman Egypt and the Mediterranean.
This is what they mean:

That is why they said Barbaroi too, since that market was basically run by Cushitic Bejas who dressed like Somalis, which is said to resemble. This is the only article of clothing mentioned to be from Egypt. The others are said to be imported, the smaller cloaks as well, but from where, that is not specified. The Somali Barbaroi clothing sold in the peninsula was not stated to be from Egypt, however, IIRC. Also, the larger cloak worn by the king, as shown by the text I dropped above the one you picked, was not mentioned to be imported from anywhere.
If you want confirmation of what I am saying, here is another translation that makes the distinction clear to show how the text does not contradict me, whatsoever:

In the same section, it mentions raw artifacts with attribution to their production origin, Diospolis. And the Barbar clothing worn by the Bejas of that region was imported from Egypt.
These two illustrations below are distinct from what the Habash nobility and priests wore, showing the diversity:

These are clearly local types.
Anyway, this deviates from the central point. Which was these were endemic developments that passed down for over 2000 years, even if the original cloak style was of a foreign inspiration and import. Even if these people were given cloaks shipped from Amazon by Egyptians (which they were definitely not), cloak making became an indigenous process for over two millennia, which was my point. This was a Habash process, so the picture where these Somali guys had on that type of clothing was taken from the Habash culture. I want us to use our clothing, not take on the clothes of people we historically were distinct from and often competed and even fought against. It's like Turks rocking Greek cultural clothing. It's a symbol for cultural domination.
