Where Group throttle by(Regeln für die Gruppendrossel): is by page

Group throttle by(Regeln für die Gruppendrossel): page; The setting is by obiviously by page. Say I am user(name):ABCD and I am editing page/article named PQR . The Number of actions to allow(Anzahl erlaubter Aktionen:): is 3 and I make 4 edits on article PQR Then I go to page/article XYZ and I make only one edit on article XYZ.

In this case since on page/article XYZ only one edit and simply no other action. My experience and obsrvation is still the filter is counting and throttling this action on article XYZ. Where as as earlier said, If Group throttle by(Regeln für die Gruppendrossel): is by page I expect filter to wait until my 3 actions on page XYZ are completed, But the filter is not waiting so is this a software bug or need of edit filter software enhancement ?

For exaple please see edit filter log https://mr.wikipedia.org/wiki/विशेष:संपादनगाळणी_नोंदी/61096 and concerned user contributions on 2nd may. The given filter no 127 on mr wikipedia was supposed to trigger after 4 actions but actually it triggered on first action itself on the given article page.

I am unaware, if, bug no T100638 and this one are, techanically part of same problem or different.
