Well as it's an A345 that is the subject of this incident how about a quote from A345 FCOM 3.03.22 titled Crosswind Landings?
Crosswind Landings:
The preferred technique is to use rudder to align the aircraft with the runway during the flare whilst using lateral control to maintain the aircraft on the runway center-line.
For crosswind landing routine use of into wind aileron is not recommended because sidestick deflection commands roll rate until touchdown.
In strong crosswind conditions, small amounts of lateral control may be used to maintain wing level. The lateral stick input must be reduced to zero at first main landing gear touchdown.
What is good for a 777 Wiley 'ain't good for the Bigbus... The technique works just fine I assure having done it myself in many a strong crosswind
Besides - I found that the wing down, cross control technique very effective in a C-152 all those years ago
