It sounds like you and the book are saying the same thing.
1 = "new PTR defined in control block; write there". The key is "new sequential pointer", meaning the value of PTR is changed to be that in the control block.
2 = "ignore any PTR in control block; write to current PTR". The key is "ignore" meaning any value of PTR in the control block is ignored. This is only an "append" if PTR == EXT.
