Using this phrase is an instructing technique to get students to stop landing in a too-flat-attitude...but,wait, you knew that didn't you?
I prefer dealing with a student honestly, and calling a spade a spade. If I mean a nose-high attitude, then I tell the student nose high attitude.
Particularly with a new student or any primary student, telling the student to land the airplane like a taildragger has no meaning, if the student is flying a tricycle gear airplane. The student has no experience with which to correlate such an example, except perhaps having seen one on the ramp...this does little good in the cockpit.
If the student has a particularly hard time getting it, I'll tie the tail down and lift the nose and let the student sit in the airplane for an hour before we fly, visualizing the landing, then opening his eyes and seeing the landing attitude.
I'll do the same thing in a conventional gear airplane. In order for the student to visualize and understand a wheel or two point landing, I'll raise the tail of the airplane and place it in a truck bed or on a stand, and have the student sit in the airplane while mentally "flying it." The student gets the sight picture so that it's more familiar to him or her when we land. The student may go back and do this several times, as needed.
I explain to a student wile taxiing in a tricycle gear airplane that this is a three point attitude. Look outside, memorize how close you feel to the ground while moving...this is very close to what you'll see on landing, but with the nose in the air, just like it was when you were at the ramp with the tail tied down (or raised for a conventional gear airplane).
If I'm taxiing with a student in a conventional gear airplane, then yes, I can tell the student that we are experiencing the same proximity to the ground, in a three point landing attitude, that the student will experience when he or she lands.
I do not try to help a student in a tricycle gear airplane understand a landing by using incorrect terminology and poor examples, and by confusing the student using aircraft configurations and feelings and sight pictures that he or she has never experienced.
