Actually, it happens not because of the lack of refactoring (since they're just blocks). How many "}"s are placed at the end of Java code wouldn't matter much, but because the syntax in Ruby tends to be simpler and cleaner than some of those redundant, a sequence of the "end" keyword to denote the end of blocks look somewhat conspicuous.
In reality, I actually liked Ruby lots, but just wanted to tease Datschge and posted one of what I disliked about it ;p
