On macOS, assignment for left-command key is controlled
by that for right-command key.

  GNU Emacs 26.1 (build 1, x86_64-apple-darwin14.5.0, NS appkit-1348.17 Version 10.10.5 (Build 14F2511)) of 2018-05-31
  macOS Mojave 10.14.3
  Mac mini (2018)
  
  /Applications/Emacs.app/Contents/MacOS/Emacs -Q
  C-h k leftcommand-x
  s-x runs the command kill-region (found in global-map),...
  M-: (setq ns-right-command-modifier 'meta)
  C-h k leftcommand-x
  M-x runs the command execute-extended-command (found in global-map),...

This does not happen with Mac mini (2012) with other parameters and
the same keyboard.
