Powershell Bad Code #3: Operator "or" in switch statement

Question: Why this code doesn’t display “Found” if the value of the variable $log is 4797 ?

Not working

$log = 4797

switch ($log) 
{
    ((4797) -or (4672)){'Found'}
}

$log = 4797

switch ($log)

{

((4797) -or (4672)){'Found'}

}

Working

# Answer:
$log = 4797

switch ($log) 
{
    {$_ -eq 4797 -or $_ -eq 4672} {'Found'}
}

# Explanation: It is needed to use $_ in the switch statement.
