Splatting – over complex?

I’m trying to tidy up a script for production and I’d like feeding if the following is over complicating the use of splatting? The original example came from Mike Robbins – http://mikefrobbins.com/2013/05/23/2013-powershell-scripting-games-advanced-event-4-auditors-love-greenbar-paper/

$LDAPGroupFilter = "(&(objectcategory=group)(objectclass=group)(mailNickname=*)(!mail=*@internal.com)(!cn=zzz*)(!cn=l-*)(!cn=g-*))"

$UserParameters = @{
	Filter = 	    $LDAPGroupFilter
	Properties = 'GivenName',
	             'surname',
	             'cn',
	             'mail',
	             'proxyAddresses'
	ErrorAction = 'Stop'
	ErrorVariable = 'ADIssueGroup'
}

$Group = Get-ADGroup @Params 
$Params.Property = $Params.Properties  
$Params.Remove("Properties")     
$Params.Remove("Filter")       
$Group | Select-Object @Params
