potential docs update needed for GuardLifetime?

The documentation for the GuardLifetime torrc option says:

If nonzero, and UseEntryGuards is set, minimum time to keep a guard before
    picking a new one. If zero, we use the GuardLifetime parameter from the
    consensus directory.  No value here may  be less than 1 month or greater
    than 5 years; out-of-range values are clamped. (Default: 0)

In commit hash 385602e9826e79dbf0d8b51abfd925e59f275708 it appears that there was a behavior change which allows guard lifetimes of 1 day or greater (grep for get_options()->GuardLifetime >= 86400). git blame indicated the docs for the GuardLifetime option haven't been touched in 6-7 years, so I think they need an update after this change.

Is the expected behavior that setting UseEntryGuards 1 and GuardLifetime 1 day will result in guards being used for no longer than one day?
