Why are my list.view.query changes not being committed?

Question

I'm using powershell to try to change the query for every view called either 'View Title 1' or 'View Title 2' in every list called 'News' in every subsite.

The script doesn't throw any errors but the views are not being updated.

Here is my code:

param($url = "")

if ($url -eq "") 
{ 
    Write-Warning "Specify a URL: -url ""http://site"""
    exit
}

Function ReadWeb($web)
{
    foreach ($subweb in $web.Webs)
    {
        ReadWeb($subweb)
    }
    for ($j = 0; $j -lt ($web.Lists.Count); $j++)
    {
        ProcessList($web.Lists[$j])
    }
}

Function ProcessList($list)
{
    if ($list.title -eq "List Title")
    {
        Write-Host "Processing web:" $list.ParentWebUrl
        for ($i = 0; $i -lt ($list.views.Count); $i++)
        {
            if ($list.views[$i].title -eq "View Title 1")
            {
                write-host "Updating view:" $list.views[$i].title
                $newQuery = '<CAML Query 1 />'
                $list.views[$i].Query = $newQuery
                $list.views[$i].Update()
            }
            elseif ($list.views[$i].title -eq "View Title 2")
            {
                write-host "Updating view:" $list.views[$i].title
                $newQuery = '<CAML Query 2 />'
                $list.views[$i].Query = $newQuery
                $list.views[$i].Update()
            }
        }
    }
}

$siteCollection = Get-SPSite $url
$WebApp = $siteCollection.WebApplication

foreach ($Site in $WebApp.Sites)
{
    foreach($spWeb in $Site.AllWebs)
    {
        ReadWeb($spWeb)
        $spWeb.Dispose()
    }   
}

EDIT - working code:

Function ProcessList($list) {     
    if ($list.title -eq "List Title")
    {         
        Write-Host "Processing web:" $list.ParentWebUrl         
        for ($i = 0; $i -lt ($list.views.Count); $i++)         
        {
            $currentView = $list.views[$i]
            if ($currentView.title -eq "View Title 1")             
            {                 
                write-host "Updating view:" $currentView.title                 
                $newQuery = '<CAML Query 1 />'
                $currentView.Query = $newQuery                 
                $currentView.Update()             
            }             
            elseif ($currentView.title -eq "View Title 2")             
            {                 
                write-host "Updating view:" $currentView.title                 
                $newQuery = '<CAML Query 2 />'                
                $currentView.Query = $newQuery                 
                $currentView.Update()             
            }         
        }
        $list.update()
    } 
}

Try to assign the view to a variable inside the loop, as @james-love suggests here Why can't I update an SPView query?
