Logic question regarding RESET?

this is the truth table I have when Reset=0 (JK flip flop)
R I0 I1 Q0 Q1
0 0 0 1 0
0 0 0 1 1
0 0 0 1 0
0 0 0 1 1
0 0 1 0 0
0 0 1 1 0
0 0 1 0 1
0 0 1 1 1
0 1 0 1 1
0 1 0 0 0
0 1 0 1 1
0 1 0 0 0
0 1 1 0 1
0 1 1 0 0
0 1 1 0 0
0 1 1 0 1
0 1 1 0 0

What happens when Reset=1? Output =0?

according to this link and my code, which agrees,
Code:
┌─┬─┬─┬──────────────────────────────────────────────┐
│J│K│Q│(J and not Q) or ((not K) and Q) JK Flip Flop │
├─┼─┼─┼──────────────────────────────────────────────┤
│0│0│0│0                                             │
│0│0│1│1                                             │
│0│1│0│0                                             │
│0│1│1│0                                             │
│1│0│0│1                                             │
│1│0│1│1                                             │
│1│1│0│1                                             │
│1│1│1│0                                             │
└─┴─┴─┴──────────────────────────────────────────────┘
   

clearly,
j=1 k=1 q toggles,
j=1 k=0 q sets
j=0 k=1 q resets
j=0 k=1 q holds.
