I would use [[ instead of [
J dictionary didn't say much on side effects.

first is
noun verb verb(v c v) noun NB. parses all 4 terms.
second is
n v v v n NB. parses rightmost 4 terms.
And when that gets reduced to n v v n the rightmost n has already been executed
along with its side
The rules are given in the parsing table

I see. It has to parse the value of COUNTER at parse time? for:
COUNTER [ CNT@{. 1 2 3 [ COUNTER =: 0
but It is harder to see why the same rule wouldn't apply to the left COUNTER
here:
COUNTER [ ] CNT@{. 1 2 3 [ COUNTER =: 0
1
If COUNTER needs to be checked for whether it is a conjunction,
CNT =: 3 : 'y [ COUNTER =: >: COUNTER'
COUNTER [[ CNT@{. 1 2 3 [ COUNTER =: 0
1
In the general case, COUNTER might have instead been a conjunction,
which would have meant that the [ to the left of CNT in your
expression would have been an argument to that conjunction, instead of
being a
CNT =: 3 : 'y [ COUNTER =: >: COUNTER'
COUNTER [ CNT@{. 1 2 3 [ COUNTER =: 0
0
COUNTER
1
workaround
3 :'COUNTER' [ CNT@{. 1 2 3 [ COUNTER =: 0
1
J is being too smart in short circuiting constant [ at console (jqt)
