This is showing how you have to take into consideration input frequency for a edge detector circuit.
Given enough time if the cap is discharged every change from +10 to -10 and vice versa will move the cap 20 volts which will then discharge through one of the diodes. If you make your time constant so high the circuit will never discharge and reach its steady DC state where it becomes some weird divider like >>1476863
