Contingency - more than one spell?

[Deox]

What would the ramifications be should a wizard be able to "hold" two contingent spells? Assume the rules of concentration still applied.

What would be some ideas or combos you would use?

Addendum: What if the wizard in question could hold 3 contingencies?

I don't see how you addendum differs from your question. 3 is also more than one.

Clear in my head, though not in writing.

Question would be - Two contingent spells. Addendum - Three contingent spells. Will edit OP for clarity.
