V-brake shoe question

Hello,

There is one thing that always puzzled me with V-brake shoes. There is
one thing that I like with these modern brake shoes, which is that their
attachmend to the caliper offers less degrees of freedom than the one of
cantilever brakes, which I found very hard to adjust correctly.

To keep some degree of freedom in roll and yaw (I take the bicycle as a
reference to name these), the V-brake shoe bolts are equipped with two
pairs of rounded (concave and convexe) bushings. One of these bushing
pairs is longer than the other, and the longest one is supposed to be
installed on the internal side. When the brake pads are new, this leads
to the caliper arms forming a \ / shape rather than a | | shape. For
some reason, I do not like that, and I always swap the bushing pairs to
put the shortest one inside. Am I wrong to do so, and is there a reason
to mount the caliper arms in a \ / shape ?

Bicycly,
