If that was the case, most other teams Guernsey would need to be included as wellFunnily enough I came to this thread for the exact same reason the gentleman raised in the video. He might not have explained it correctly, but he is correct.
The Eagles have three designated guernseys for season 2018 - home, away and clash.
The home is as on your site, with SGIO front logo and HJ back logo
Away is same design as home, but HJ logo front and SGIO logo back. It is an official away guernsey.
Clash is gold, as on your site.
They don't sell a retail version of the away.
If we pretend the guernseys on your site have their sponsor logos on them, the 2018 away is an omission.
Gary Stocks, club spokesman said at the launch of the new guernseys:

To be accurate, you just need to add the 'home' design to the away page as well, and say they used the same design for home and away.
