Yes, that was not good, but in "my method" We do both ECAM and paper procedure, only we don't go around prematurely if fuel is a factor.
As I look at it, you can configure to CONF 3, in the meantime calculate VAPP, which is FMGC VAPP + ECAM's delta VREF (it should be exactly PFD's VLS), then select that speed, then go throuh the procedure for Go around possibility.
If you go below 1,000 ft without having done all this, then go around. If you have, don't forget landing clearance, landing checklist, then land. All safe and according to procedures.
