AND operation on sequences in assertions

In reply to ben@SystemVerilog.us:

Hi Ben,

Thanks for the reply.
I still didn’t get it.

“The composite sequence completes and matches when there is a match in both subsequences, and the longer sequence completes”. This means when two subsequences match then only whole composite sequence gets matched right?.

I am not getting why there is match in 13th clock for composite sequence even there is no match in one of the subsequence.

Thank you
