You can't, the condition refers to the whole method call. As an example:

#------------
condition = true
[1, 2].each do |i|
  puts i
end if condition
#------------

If the condition is met, then the elements of the array will be printed. 
This is the same as wrapping the method call (with the block) into an if 
statement:

#------------
condition = true
if condition
  [1, 2].each do |i|
    puts i
  end
end
#------------

Since the first variant is obviously hard to read and can be 
misunderstood, you should definitely rewrite the code to the second 
variant. It may be a bit longer and less "cool", but you can understand 
it without playing parser first.

Yeah, it would have been better if you'd attached the file.
