Some people scroll through the list to get to the weapon they want rather than using the number keys to switch. (Mainly those who use the directional arrows for movement) With autoswitch enabled, it prevents the lastinv command from being used effectively. (weapon 2 chosen, scroll through to select weapon 4, lastinv with autoswitch on would switch back to weapon 3 rather than 2).

I'm sure I'm in the minority though and I or others could always disable autoswitch. Since most people probably use WASD for movement and numbers to switch weapons, autoswitch should be enabled by default.
