Cash spoils after eliminating an opponent

[Geger]

I forget about this. After eliminating someone and collecting his spoils I have only 4 spoils but luckily have a set. Can I cash the spoils now?

From Help Menu I find only this :

If by eliminating someone you have five or more spoils you are then forced to turn at least one group in but you can turn in as many groups as you have available.

You can only cash in the middle of your turn if you have 5 or more spoils. At that time you may cash as many sets as you have.

I see, thank you
