Yeah, pretty much. They think that just because there may be some vague reference to Yeshua, the Christ, or the followers of same, that it is proof that the whole Christ story is true and for reals. They fail to take into account that it isn't any more relevant to proving the Jesus myth than someone putting a cross on their tombstone today or having a Christian themed casket. Just because the deceased (or those burying the deceased) believe in something doesn't make it true.
