Aspose PDF WatermarkArtifact is not consistent for multiple pages

I Am using Aspose PDF for dotnet and I use WatermarkArtifact class to apply watermark by following this link https://docs.aspose.com/pdf/net/add-watermarks/#programming-samples-how-to-add-watermark-on-pdf-files.

I have applied watermark scopes like rotation, opacity, stroking color. But all these scopes are applied only to the first page. Second page in PDF does not maintain the same rotation or

Below is the code

		private void InsertWatermarkText(Aspose.Pdf.Document document)
			WatermarkArtifact artifact = new WatermarkArtifact();
				"Preview Only",
				new TextState()
					FontSize = 72,
					ForegroundColor = Color.FromRgb(System.Drawing.Color.Green),
					Font = FontRepository.FindFont("Arial"),
					StrokingColor = Color.FromRgb(System.Drawing.Color.Green)

			artifact.IsBackground = false;
			artifact.Rotation = 45;
			artifact.Opacity = 0.5;

			// Place the watermark in the page center.
			artifact.ArtifactHorizontalAlignment = HorizontalAlignment.Center;
			artifact.ArtifactVerticalAlignment = VerticalAlignment.Center;


			for (int i = 1; i < document.Pages.Count + 1; i++)
