Control-break"ish" in awk

Hi,

input:
Code:
1|Bob
2|Bob
Ref|Bob
3|Rick
7|Rick
Ref|Rick

I am trying to append a "*" field to the record containing "Ref" in $1, only if the previous $1 with a common $2 have a value <4.

ouput:
Code:
1|Bob
2|Bob
Ref|Bob|*
3|Rick
7|Rick
Ref|Rick

The first subgroup ("Bob") shows $1 with only values <4, so a "*" is appended at the record "Ref".
The second subgroup ("Rick") shows one value >4 and is thus unchanged.

I read a couple of tutorials dealing with control-break programs, but they are all for counting (which is not my goal).

If someone could put me on track :-)

My attempt so far:
Code:
BEGIN{FS=OFS="|"}
{a[$2]++}
END{
   for(i in a){
      if($1 <4){
         if($1 ~ /Ref/){print $0 "|\*"}
      }
      else{print $0}
   }
}
