You can certainly find snippets that are simpler in Ruby than in Python; they're just not the majority. Consider a slightly more complicated case where you need to print out items in a range with some modification. Idiomatic Ruby:

   (0 ... 5).each do |x|
     print (x + 1)
   end

Idiomatic Python:

   for x in range(0, 5):
     print (x + 1)

To understand Ruby, you need to know what || does, and the overall sequencing of the words as you read that construct is somewhat unnatural for English. Python is comparatively easier to parse with no prior background.

It is definitely possible to write Ruby in a way that's still highly readable. But from what I've seen of real world Ruby code, that's not the way it tends to be written - idiomatic Ruby values expressiveness and DRY, so you see blocks and various terse syntactic sugar used all over the place; lots of "clever" code in general. There's nothing wrong with that - I generally prefer expressiveness over readability myself - but many people do not.
