I wouldn't consider it a Secret Boss. I prefer to think of it more like those surprise encounters in games that you have no chance of winning (due to always being more powerful then your party can possibly be)

If it was an actual bonus boss, then Seiya would have had to defeat it after getting past the Demon Lord before he could return home again.
