My reading of the source to init(8) is that
	a) the record for "line" in /var/run/utmp is updated to have a
	   cleared user and host field, and the current time.
	b) a new record is appended to /var/log/wtmp with the line,
	   a cleared user & host field, and the current time.

So, your comment is more an addition to what's there, rather than a
replacement. A rewording of both is in order. I'll do this, and commit
the result, and if it's not clear enough, then you can fix that ;)
