[Mne_analysis] Issue with example in mne.datasets.eegbci.data_path()

[Ramiro Gatti]

        External Email - Use Caution        

Yes, that way
<https://mne.tools/dev/generated/mne.datasets.eegbci.load_data.html#mne.datasets.eegbci.load_data>
it works. But theoretically the other script should also work based on
the description
of the function
<https://github.com/mne-tools/mne-python/blob/22dfbb5c55f09b88f595dd5c6d83dac71335df97/mne/datasets/eegbci/eegbci.py#L46>.
I do not understand what is wrong.
