Run cron command twice

[bh-ref]

http://devdocs.magento.com/guides/v2.0/config-guide/cli/config-cli-subcommands-cron.html contains a hint that cron should run twice. This is at least true for the command php bin/magento cron:run.

Two questions:

1. Is this also true for the other two mentioned commands:
   <your Magento install dir>/update/cron.php
php bin/magento setup:cron:run
   Do they also have to run twice?

2. Shouldn't the example code on that page thus actually list the command
   */1 * * * * php -c /etc/php5/cli/apache2 /var/www/html/magento2/bin/magento cron:run
   twice?

Yes, cron must run twice in all cases. I'll check to make sure it's mentioned everywhere

For #2, no. cron run from a crontab runs every minute (in that example); thus, you must wait two minutes after every eligible change. But you shouldn't list a command in a crontab twice.

I double-checked and this note is present in all the topics about cron. Closing. Please reopen if you disagree.
