Dual failure of the locking mechanism is extremely unlikely. These are not switches that are regularly used so a muscle memory issue also seems very unlikely (but is still the most likely non-suicide scenario)

If the switches have an unknown design flaw then it’s unknown how likely it is they’d both fail simultaneously

My understanding is these switches are used routinely during the shutdown procedure or did I get that wrong?

These switches are used at the end of literally every flight

The biggest problem with these theorising comment threads is the confidence people who know nothing about flying spout their theories
