Actually, the scheduler completely ignores the global:

Time to record before start of show (secs)
This global setting allows the recorder to start before the scheduled 
start time. It does not affect the scheduler. It is ignored when two 
shows have been scheduled without enough time in between.

and

Time to record past end of show (secs)
This global setting allows the recorder to record beyond the scheduled 
end time. It does not affect the scheduler. It is ignored when two shows 
have been scheduled without enough time in between.

The "recorder" may use them.

Yeah, basically.  The "Time to record before start.." applies only to 
first use of a tuner and "Time to record past end..." applies only to 
last use of a tuner in a string of back-to-back recordings with that 
tuner.  I.e. it's little more than a placebo and (as you said) should 
never be expected on any recording.  If you want to record extra, you 
should tell the scheduler to schedule that time and have sufficient 
tuners to record what you want.
