I would argue two reasons.
First, it does not accomplish anything. The crew did not intentionally do this. I think the only time it makes sense is if the person willfully ignored procedures without a valid reason. It is important to apply local rationality, "why did it make sense for the person to do what they had done at the time".
Second, this is clearly a system issue. Missing the radio call was almost certainly due to some inadvertent action on the part of the pilot or something in the equipment design. Humans work around these issues constantly, but sometimes we are not able to for various reasons. This is a highlight of a design issue for either the equipment or the system as a whole, or, more likely, both.
The fact that others have been able to compensate for it does not mean that a failure won't happen eventually. One of the aspects that led to the AS 261 accident was that the service panel for the jack screw was too small to see in when your hand was in the hole to service it, so you had to do it by feel. Eventually that led to an accident, but for many years people were able to adapt to the poor design.
