If like from Nick Edwards suggested a imapproxy is used it will.
imapproxy is keeping the connection open.
doveadm who will give you a list of all actual logged in users.
Without imapproxy you are right: Every page reload will cause a login
and a logoff. I get some webmail users by "accident".
To get an overview how many users used roudcube within a period check
the database table users/last_login.
