My advice is to separate the plants with a reasonable amount of root
attached - I would advice a minimum of a few Cms of root. If this means
you have several plants per piece of root this should not be too much of
a problem. Eventually the plants will produce their own roots anyway,
whether you separate them or not. All separating them will do is
possibly encourage them to form their own roots quicker.

I agree with your observation about P. lusitanica being self
pollinating. This is most unusual with Pinguiculas since they mostly
have flower structures specifically to prevent self pollination. I have
never dissected a flower of P. lusitanica to see if the same structures
are present. Perhaps this would be worth doing - currently I don't grow
the species, which is excuse enough for me not to volunteer. :-)
