isis redistribution l2 to l1 neighborship

Trying to do redistribution lab but have a doubt that is bugging me for a
while.

scenario:
distribute L2 into l2 between R1 and r2. R1 is L1L2 (default) bb router. L1
is branch (l1 only).

R1---s0/0-------s0/0-------R2

R1 = backbone(L2|L1 default)
R2 = branch router (L1 only)

R1:

access-list 102 per ip an an

router isis
 net 47.1111.0000.0000.1111.00
 metric-style wide
 redistribute isis ip level-2 into level-1 distr 102
int fas0/0
 ip router isis
int s0/0
 ip router isis

R2:
router isis
 net 47.1111.0000.0000.2222.00
 metric-style wide
 is-type leve-1
int fas0/0
 ip router isis
 isis circuit-type level-1
int s0/0
 ip router isis
  isis circuit-type level-1

Question: When i issue show clns neigh on R2 , i see level-1 neighborship
between R1 and R2. (As expected)

But
If i remove is-circuit-type level-1 from R2's fas0/0 and s0/0, clear
neighborship, shut serial0/0 and no shut. i still see isis neighborhsip
with is-type level1.

a) So whats the relationship between --> is-type under 'router isis' and
'isis circuit-type' under the interface?
b) Is my config for redist correct?
