[Mne_analysis] ICA mne python - combining mags and grads

Hello everyone,

I have an ICA-related question for the mne-python community. This time 
more theoretically oriented.

All examples and tutorials on the mne python pages for ICA artefact 
rejection procedures combine both magnetometers and gradiometers 
together when performing ICA and finding artefact components. What would 
be an argument for combining all sensors like this as opposed to doing 
ICA on grads and mags separately (which seems to be a recommended way in 
other packages)? Is this simply for saving computational time?

Thanks for your advice!

Ana
