It makes no sense

the wall is heading in the direction of the black gate where it would connect with the fort. In fact the line of west gate road would put the wall reaching even a little to the south of the black gate nearer to the castle keep.

The accepted line is that it passes somewhere near the cathedral or Amen Corner, some way to the north. If it went as far south as the Black Gate (for which no evidence has been found), it would then have to climb north again with an uncalled-for re-entrant in order to line up with known stretches of curtain wall around Melbourne Street. There remains no evidence that the fort was attached to the curtain wall.

We'll have to hope the Hadrian's Wall Quest project turns up some new evidence. In the end, speculation (like resistance) is futile.
