Airbus calls the spar valve "LP fuel shut off valve"
FCOM DSC-70-40: Shut-Off Valves
"Moving the ENG1 (ENG2) MASTER switch to OFF directly commands the closing of the LP and HP fuel shut off valves for that engine's fuel system.
It also closes the fuel return valve and opens the bypass valve."
Apparently Airbus finally wised up and made a change to close the "LP valve" because it didn't use to be that way (A300, A310, at least some early A320).
Not that Boeing didn't do the same thing - early 747s didn't close the spar valve either - after a number of hot starts/tailpipe fires they changed to shut down both valves.
