Well, in this case, squeeze and strip is almost the same, 
because later, you will split on space char. 
( so squeeze space between first and second item is not a problem at all )
 
The only problem on squeez is ONLY on the last item
'  A  B      C    D    E' after squeeze.split(' ', 3) ==> ['A', 'B', 'C D E ']
last item ( middle and tail will squeez! )
 
An avantage squeeze then strip is like, if you want :
irb(main):002:0> 'A,,,,B,,,,,C,,,D,,E,,'.squeeze(',').split(',',3)
["A", "B", "C,D,E,"]
# can strip do that ?! :-)
 
Anyway, you need more control, still need to work on last item after split.
