Subject: Can't understand String#split's behavior

When I use ruby 1.8.7 I have a problem with String#split.

It's fine:
>>p "bAbAbAb".split(/A/)
["b", "b", "b", "b"]

But it cant work:
>>p "bAbAbAb".split(/(A)/)
["b", "A", "b", "A", "b", "A", "b"]

I think that /A/ and /(A)/ are almost equivalent, but why can't I use /(A)/
to split string?
