[Not Working] Set-PSBreakPoint when a variable becomes $false

So I'm looking at a script from the Windows PowerShell Cookbook by Lee Holmes call Enable-BreakOnError and I want to do something similar by using Set-PSBreakPoint on a variable but only break when the variable is set to False. Here is Lee's function:

<#  .SYNOPSIS  Creates a breakpoint that only fires when PowerShell encounters an error  .EXAMPLE  PS >Enable-BreakOnError

ID Script           Line Command         Variable        Action
-- ------           ---- -------         --------        ------
0                       Out-Default                     ...

PS >1/0
Entering debug mode. Use h or ? for help.

Hit Command breakpoint on 'Out-Default'


PS >$error
Attempted to divide by zero.

Set-StrictMode -Version Latest

## Store the current number of errors seen in the session so far
$GLOBAL:EnableBreakOnErrorLastErrorCount = $error.Count

Set-PSBreakpoint -Command Out-Default -Action {

## If we're generating output, and the error count has increased,
## break into the debugger.
if($error.Count -ne $EnableBreakOnErrorLastErrorCount)
{
    $GLOBAL:EnableBreakOnErrorLastErrorCount = $error.Count
    break
}
}

Seems simple enough. So I set up a script to test my idea, and I cannot get it to work at all. Here is how I am testing this:

$Value = $True

Set-PSBreakpoint -Variable Value -Mode Write

$Value = $False
$Value = $False
$Value = $true
$value = $true

Get-PSBreakpoint | Remove-PSBreakpoint

So in using -Mode Write, this stops execution immediately before a new value is written to the variable, so it stops every time. This does not work for me because I need to know what $value is being set as, but it breaks before it is set. Is there a magical way around this?
