In the above statement there was a "?", which is missing here.

It should read:
"in this case 11111111.11111111.11111111.11111111 has no bits set to
right of 8th Least Significant Bit???"
(with a ^ showing the position where the mask ends, making it
obviously visible to the ones who use text base MUAs in fixed width font
terminals).

In other words, why doesnt the system produce an error for the second
query as well???

Others (Marcus) have reported that the second query
SELECT '255.255.255.255/25'::cidr;
indeed produces an error in 8.1;

so i guess its a bug in the 7.4.x series.
