LM2903-Q1: how to understand parameter Vicr(common-mode input voltage range)

Part Number: LM2903-Q1

dear expert:

i cannot understand Vicr on page5 of LM2903-Q1 datasheet. can you kindly correct me please?

1. does "0 to VCC-2" means that, both non-inverting input and inverting input should in the range of 0V to VCC-2V?

2. can you detail note3 please?

"The voltage at either input or common-mode should not be allowed to go negative by more than 0.3 V. The upper end of the commonmode voltage range is VCC+ - 1.5 V for the inverting input (-), and the non-inverting input (+) can exceed the VCC level; the comparator provides a proper output state. Either or both inputs can go to 30 V (32V for V-suffix devices) without damage. "
