Repository is not pulled when Bedrock is deployed using Capistrano to staging

Bedrock installation is deployed from local dev station to staging on hosting.
set :repo_url is set in deploy.rb and git commands seem to succeed when bundle exec cap staging deploy:check and bundle exec cap staging deploy are run.

However, i still need to git pull on staging to get the latest repo changes.
Should staging be additionally configured somehow so that the above deployment commands would update the repo?
