Good to share this (Forwarded email by Louis)~
Main reason is, if you keep the cover open while you flush it, the bacteria/microorganism can travel up to 6m in the air, stay for few hours, and get contact on wall or other thing subsequently.
That is why we should cultivate our habit to close up the toilet bowl's cover before you flush to avoid those bacterias go into your mouth through your tooth brush. :p
