You have to manually turn the X-Bleed knob to OPEN.
It's not automatic ! Imagine ie. Eng FIRE or BMC1 fault ( A320 APU's bleed pipe is on the left pipe line side compared to X-Bleed Valve POS.)
Please follow QRH Procedure. Normally Windmill Quick relight works with airspeed 300kt.
PS. It's the same way when you perform X-bleed engine start on ground 1. APU bleed off (ensure engine bleed off) 2. Manually X-bleed OPEN.
