I guess the logic is that once you have a well covered/balanced defense(4 is enough),3 Strikers should not scare you that much if you hit your opponent right before,in the midfield.
so basically the 4-1-4-1,against that 4-3-3 gives you +1 advantage in the midfield,So it makes sense to me.your opponent might succumb right there.Personally i scored big even playing with just 1 Striker,so i can tell the match is mostly decided in the midfield,combined with the right tactic/orders.Always supposing that both of the teams have the same skills or kind of.Plus that formation doesn't even have any wing...i would hit him down on the flanks!
