Which bits, exactly, does "bits 0,2,4", etc. refer
to?
Jon and I number bits LSB (least significant bit first).
Consider one of your eamaples:
_____ 987 654 3210 _3210
A1:ON 000 000 1111 (1010) binary
I put the numbers of the data bits in red above the data bits and the numbers of the check bits in green above the check bits.
So when Jon said "check bit 0= XOR of data bits 0,3,4" he means that the XOR of the bits marked with the red 0, 3 and 4 (which are 1, 1 and 0) is the value of the bit marked with the green 0 (which is 0).
