Not impossible just not as likely to happen as it is using a tubeless tubular setup. IMHO Orange is a better sealant than most that people use and I have had better luck with it so not completely surprised.
Many still run sealant in their cross tubulars that run latex innertubes as well. Sometimes it works - sometimes it doesn't.
In the end though you are sealing an innertube - not the tire. It would be like running sealant in a tube in a regular clincher setup. The fun part is when it doesn't work and then all the sealant comes out through the sidewalls around the entire casing as most casings are not air tight. fun stuff.
