From where you picked this shiva.

It's seeming senseless.

MSB talk about sign bit so sign  flag value is bit position dependent (MSB)

Auxiliary carry flag is  about extra carry bit from lower nibble to higher nibble so this is too bit position dependent

but Parity flag and zero flag don't just depend on one bit position. We have to know whole ALU o/p then only we can tell the value of these flags..
