To be precise, it is the default in:
(this was done for a future-but-yet-to-come scheme to let one specify
default methods in a R config file ... possibly the setHook methods can

'normalize' just performs the 'normalization' step (or whatever name you
may want to give it) at the probe level.
'rma' does the full monty: from raw probe level data to probe sets
expression values. This is mainly a handy wrapper for the function
'expresso' with the set of pre-processing methods proposed by the rma
