SN74HCS74-Q1: Function table Condition 6

Part Number: SN74HCS74-Q1

Hello,

I have query regarding condition 6 from the function table, it does tells the output will be the previous state.

As this SN74HCS74QPWRQ1 IC has 2 channels, the Q' for two channels shows different behaviour.

The conditions are simultaneous on each channel.

For condition at Channel 1, PRE': H; CLR': H; CLK: L; D: X -->> Q': H and Q: L.
For condition at Channel 2, PRE': H; CLR': H; CLK: L; D: X -->> Q': L and Q: H.

Why is it so? Why channel 2 has different outputs for same condition as channel 1.
How they are defined internally?
