Subject: Why `10` not returned without the `return` from the block ?

CODE - I

class Fixnum
alias other_s to_s
def to_s
a = self + 5
return a.other_s
end
end
#=> nil
puts 5
10
#=> nil

CODE - II

class Fixnum
alias other_s to_s
def to_s
self + 5
#return a.other_s
end
end

puts 5
#<Fixnum:0x00000b>
#=> nil

What I know that block returns automatically its last expression. Why
does `10` not the returned
here, rather `#<Fixnum:0x00000b>`?

But with the `return a.other_s` `10` printed - what is the concpetual
difference between CODE-I and CODE - II?

Please help me to understand.

Thanks
