Question about TH/ND

I've a question -- one of those ones that crops up when learning from old books without a teacher.

What's the distinction between the under-TH and the ND/NT combined stroke? I've just come across this (while learning the Diamond Jubilee version of Gregg), and there's no mention of how to tell them apart.

I'm tempted to start forming the shape for NT/ND/MT/MD with a flat line (either short or long, depending), but a) I don't want to start breaking rules before I've learned the proper method, and b) I want to be able to continue reading the shorthand provided with the exercises.
