Here the cluster that contains 1 has size 19, which is not much bigger than 13 obtained in (c=0.95). But remark that the order of magnitude predicted by random graph is 100^(2/3), roughly 22. Notice also how, even though the cluster is still a tree (i.e., there is no closed circuit in the component that doesn't use edges only once), it is very likely that a cycle will be created very quickly.
