This is expected. The metric is supposed to report the max amount of groups for the past week: "As a user with vertical tabs mode enabled and had at least one tab group this week, what is the max amount of tab groups this week?"

[GeetaSarvadnya]

As a user with vertical tabs mode enabled and had at least one tab group this week, what is the max amount of tab groups this week?

The max tab groups for the week is considered for the metrics response calculation hence the value 2 is expected for the 1st week, if we set the sys clock ahead by 8 days in the 2nd week the response value is 1 as expected. Hence closing the issue.
