It is simple: the Pup is on a PA of about 90 degrees (i.e. East) of Sirius A, which means that it is moving 'after' A with a steady scope, regardless of orientation or diagonals.
A trick is moving the star to the very edge of the field and let A disappear and then B should reveal briefly.
I'll try on the first night with decent seeing.
