IMO vastly more likely that Huawei wants people to -believe- they were intercepted for US intelligence, as a counter measure for the pressure they are under. In reality, US intelligence would just place someone in a FedEx facility and track down the package and do everything off the record from FedEx's tracking system. The US government is pretty incompetent, but they could easily scan all the documents without a single soul knowing or having the suspicion, even FexEx would likely not know. This is likely just a logistical change, and Huawei is trying to take advantage of it and to raise doubt.
