metrics setup does not reset prior setup

[Senthil Nathan]

Step 1 - do a metric setup as below

VBoxManage metrics setup --period 1 --samples 10 SomeVM Guest/CPU/Load/Idle*

Step 2 - query to confirm it works

VBoxManage metrics query SomeVM Guest/CPU/Load/Idle*

Step 3 - do a modified setup as below

VBoxManage metrics setup --period 1 --samples 5 SomeVM Guest/CPU/Load/Idle*

Step 4 - query to confirm it does NOT work

VBoxManage metrics query SomeVM Guest/CPU/Load/Idle*

Step 5 - do a different setup

VBoxManage metrics setup --period 1 --samples 5 SomeVM Guest/*

Step 6 - query to confirm it does work

VBoxManage metrics query SomeVM Guest/CPU/Load/Idle*

Question is, why does it not work in Step 4 - as if Step 3 did not happen, where the sample size was changed from 10 to 5? Is this a bug or is this default behavior? And then it does work when the metric is setup (reset) at the higher level.
