Now LRM P1800 clearly mentions that the signals used in an assertion are
sampled using 1step sampling. It is an error if assertion uses a signal
from a clocking block which has any other type of sampling.

I have no opinion on the issue, but as to why someone might want
assertion constructs in a clocking block, Ed previously wrote:

"I could see a case where the user has a clocking block for specifying
sampling and driving and wants to put assertions on the signals that are
marked as input, output, ... 
BUT, I hope that it will not confuse the user that the assertions sample
at 1step while the clocking block specifies some other sampling and
driving offset."
