Which version/platform? Some patchsets in O8 did strange things to inline views, for me anyways. See if it works different by aliasing the subquery: AND Pending in (Select Pending from table1 b where b.Status !=3 and b.pending !=3)
I think the way you are doing it is implicitly self-joining table1 and thereby excluding more than you want. But then again, I never do well desk-checking sql, it might be easier if you gave an example script with field and table definitions and data insertion. More brainpower might be dedicated to solving it in this forum.
