Because this is disabled by default in that mode. You can change that with
{$PointerMath On} (
https://freepascal.org/docs-html/current/prog/progsu112.html#x120-1210001.3.29
), like you can enable many other features in the more restricted modes,
but you need to do that explicitly, as there might be code breakages due to
this.
