I thought those were also a type of brackets (round brackets).

From wikipedia:

"Parentheses (singular, parenthesis) – also called simply brackets (UK), or 
round brackets, curved brackets, oval brackets, or, colloquially, parens..."

I was not wondering about what's inside the parentheses, but rather why this 
works

if (somecommand) then ...

while I would expect it should be

if (somecommand); then ...

or, alternatively,

if (somecommand)
  then ...

But as I said, I haven't checked the grammar.
