Ansible limit not match with pattern

I have inventory file as 

# file: production_hosts
[my_servers]
myserver0[1:4].google.com

When I try to run the playbook on subset of these hosts, it gives only first and last host.

$ ansible-playbook -i production_hosts -l 'myserver0[1:3].google.com' yum_update_all.yaml  --list-hosts

playbook: yum_update_all.yaml

  play #1 (all): all    TAGS: []
    pattern: [u'all']
    hosts (2):
      myserver01.google.com
      myserver03.google.com

When I tried other way, by giving each number, it gives all.

$ ansible-playbook -i production_hosts -l 'myserver0[1:2:3].google.com' yum_update_all.yaml  --list-hosts

playbook: yum_update_all.yaml

  play #1 (all): all    TAGS: []
    pattern: [u'all']
    hosts (3):
      myserver02.google.com
      myserver01.google.com
      myserver03.google.com

Pattern similar pattern hosts will not work in limit ?

ansible-playbook -i production_hosts -l 'myserver0[123].google.com' yum_update_all.yaml  --list-hosts

or (what you actually request):

ansible-playbook -i production_hosts -l 'myserver0[1-3].google.com' yum_update_all.yaml  --list-hosts

yield:

playbook: playbook.yml

  play #1 (all): all    TAGS: []
    pattern: [u'all']
    hosts (3):
      myserver02.google.com
      myserver01.google.com
      myserver03.google.com
