Board Term Limits - How can a person who ran out their years be appointed to a Vacancy?

How can a person who has served the maximum number of years be appointed to a vacancy?
In spirit this seems wrong.
I suspect there is no bylaw against it. It is a Loop Hole!
The idea of term limits is to bring in new blood.

It appears we now have 2 such person on the board.

This has nothing to do with who the persons are.
My question is more on the intent of term limits.
I think it should apply to any future appointments as well as elections.
