Bob,  that's because part of the purpose of the guard timbers, besides the 
bloody  obvious one of
guiding things along the track direction if it derails, is  to  provide 
additional strength in
holding the ties longitudinally  along the track in proper spacing, both from 
the creeping action a
train  causes (Think about when you smooth out a blanket, you push the 
material ahead  of your hand -
the weight of the train does exactly the same thing to the  rails), and from 
the sliding action a
derailed car or locomotive could  cause.  Without the lap joint (not really a 
dovetail) the  guard
timbers would pull apart at that  joint.

Yep,  I understand all that.   Just didn't know if there  were rules that 
said you had to do that, or that everyone just did it on there  own,  cause it 
was a good  practice, that helped the cause.
