1. For set_output_delay command, why the maximum output delay value should be equal to the length of the longest path to the register data pin, plus the setup time of the register ? Why the minimum output delay value should be equal to the length of the shortest path to the register data pin, minus the hold time ?

2. I do not understand why To model a later output data arrival time you must therefore decrease the output delay amount. ?
