why () is () and [] is [] work in other way?

...And Saint Adam Skutt raised the hand grenade up on high, saying, "O 
LORD, bless this Thy hand grenade that with it Thou mayest blow Thine Id 
to tiny bits, in Thy mercy." And the LORD did grin and the people did 
feast upon the lambs and sloths and carp and anchovies and orangutans 
and breakfast cereals, and fruit bats and large chu... [At this point, 
the friar is urged by Brother Maynard to "skip a bit, brother"]... And 
the LORD spake, saying, "First shalt thou take out the Holy Pin, then 
shalt thou count to three, no more, no less. Three shall be the number 
thou shalt count, and the number of the counting shall be three. Four 
shalt thou not count, neither count thou two, excepting that thou then 
proceed to three. Five is right out. Once the number three, being the 
third number, be reached, then lobbest thou thy Holy Hand Grenade of 
Antioch towards thy foe, who being naughty in My sight, shall snuff it."
