PowerShell Help

why does this script remove multiple lines

str =
@"
123
abc
456
xyz
789
"@
$str -replace "(?ms).*45",""

and output this as expected

6
xyz
789

but this script removes only the beginning of many lines

`$str = schtasks /query /fo csv`
`$str -replace “(?ms).\.\”,""`

$str = @(
'123'
'abc'
'456'
'xyz'
'789'
)
$str -replace "(?ms).*45", ""

… a kind of
