of course, this interval is rejected, because it is bad, but there
are other times, that have to be added to the end list, to determine 
with begin and dur a correct simple duration and begin and
repeatDur to determine active duration including repetition.
Just this value of the end attribute is meaningless, if the begin 
is later as end.
In the audio example dur is determined by the media itself
with an implicit end, therefore even there is no difference to 
the svg animation example.

It is just pseudo code and begin+dur or begin+repeatDur
generate further 'end's in the list. There is more than one 
time in the end list and therefore there are some 
'good intervals' to care about. 

Best wishes
