Using single capacitor w/ a dist block

Hi guys...

I was thinking about using a 1F capacitor for my 2 amps (400x1 and 40x4).  However, the manual included w/ my capacitor says to use a distribution block BEFORE the capacitor (ie, the block goes in between the battery and cap).  Are they just trying to con me into buying another one of their capacitors?  My two questions:

1) Does it matter?  Why can't I use the distribution block AFTER the cap? (ie, battery goes to capacitor which goes to distribution block).

2) If it does matter, I was thinking of using the cap solely on my 400x1 and not worrying about the 40x4 (which is high-freq filtered anyway).  Does this sound like a sound plan?

As always...thank you!
