Your colleague is correct. The 2>&1 just redirects Channel 2 (Standard Error) and Channel 1 (Standard Output) to the same place which in this context is Channel 1 (Standard Output), and thence your log file.
If all output from a cron is redirected to a file, it will not generate an email of the output to Stdout or Stderr.
Hope this helps.
