"su -" does not create a user session so the logind option KillUserProcesses (or any other option) has no effect here.

You cannot create a user session within an exisitng user session (not without complications - this is why startx itself has to inherit the existing user session and thus the type is listed as text rather than graphical and we cannot switch tty or we will lose all ACL permissions etc).

Anyway, what you are doing here is totally expected within the context of logind (i.e. logind is not used at all here).
