Why have two approach flap limit switches?

I wanted to verify that the B36TC has two flap limit switches for the approach flap setting. I can't find documentation for it anywhere. One is "on the way down" (from Up to Approach) and the other is "on the way up" (from Full to Approach). If this is the case, what is the reason behind Beech doing this?

The purpose of the 2 switches are to have the flaps stop at 15 degrees going down and coming up to approach,
The 14 degree switch stops the motor going down and flaps coast to 15 Degrees and the 16 degree switch stops the motor coming up to approach and flaps coast to 15 degrees.
All the model aircraft Bonanza and Baron starting getting approach position flaps in 1979.
The G36 uses 12 degrees and not 15 degrees for approach.
