Disable TEST API load textdomain – why wee need this?

Hi, thanks for great plugin!

I have question, why we need to disable REST API load texdomain with this code:

add_action( 'init', 'disable_rest_api_load_textdomain' );
function disable_rest_api_load_textdomain() {
	load_plugin_textdomain( 'disable-json-api', false, dirname( plugin_basename( __FILE__ ) ) . '/languages' );
}
