[FieldTrip] Baseline correction during ICA & then again before timelock?

I am using fieldtrip to preprocess (epoching, trial rejection, ICA to
remove eye blinks, etc., filtering) my MEG data and have a question
regarding baseline correction.I have noticed that, in the default settings
for ft_componentanalysis, cfg.demean is set to 'yes', so I assume that the
mean of the entire trial is subrated. What does this setting imply for
future analyses of this data (at the sensor-level), for example timelock
analyses of different conditions. Should one still implement another
baseline-correction? Why/why not?
In advance, many thanks for your help. I very much appreciate all of the
knowledge of this community!
