There are a few instructors that can apply and teach wrist locks (Nikkyos and Sankyos) correctly. When I show Sankyos and nikkyos in class, I make sure I tell the students that when uke taps, it's over immediately. If I see uke tapping and nage NOT stopping, nage sits out the rest of the class, period. After class I will talk with the nage and there will be no misunderstanding!! Nikkyos and sankyos you do not mess with. Fortunately, I have never had the above situation happen in my class.
This is an important difference with some Karate training. The two taps and a clean break are not taught in some Karate training. So it would be wise to introduce this Aikido concept, of two taps and break, to a Karate Instructor, as part of the preparation of students for wrist lock training.
