Did you actually test this?  I did, and here is what I got:

jeremyb@JEREMYB ~/tmp/test
$ mkdir -p first_level/second_level

jeremyb@JEREMYB ~/tmp/test
$ touch file.rb first_level/file.rb first_level/second_level/file.rb

jeremyb@JEREMYB ~/tmp/test
$ find .
.
./file.rb
./first_level
./first_level/file.rb
./first_level/second_level
./first_level/second_level/file.rb

jeremyb@JEREMYB ~/tmp/test
$ ruby -e 'puts Dir.glob("**/*.rb").join("\n")'
file.rb
first_level/file.rb
first_level/second_level/file.rb


The meaning of ** in the glob means to match any and all intervening
directories at that point in the pattern.  Can you explain why you think
that is not the case?
