I have no clue why they wanted their own planes grounded temporarily, but if you were top management and saw the need to do so, you would be aware of propagation delay and non-compliance in any organisation (a pilot might decide to ignore such an instruction planning to pretend they didn't get it in time, for whatever reason, like a sweetheart in a different place waiting for them). Asking the government and thus the airports and control towers to ground them acts as a second safety, whatever the concern was?
