I have wondered about this. When I bring up a connection manually which 
normally starts with auto=start in the conf file, I just do:

ipsec auto --replace (or add) my-conn
ipsec auto --up my-conn

I do not do an ipsec auto --route, but the description you have quoted 
implies you also need an ipsec auto --route. Can you un-confuse me?
