Anyone who's worked on electronics know the frustration of the "easy to insert, hard as hell to remove" type fasteners that manufacturers insist on using. Basically the exact same principle as this. Plenty of plastic casing fasteners and super tiny and delicate connectors are built like that. If something goes wrong during disassembly, at best you'll have an unsightly crack or blemish on the casing, at worst you rip an internal connector and its socket right off the circuit board along with some traces, destroying it. And getting frustrated exponentially increases the chances you'll break something.
