Are all butchers taught the same cuts?

My sister in law a native Texan now lives in Maryland and she recently went to see her local butcher to see if she could find flank steak. Since she has 5 kids and flank steak is generally a cheaper cut of meat. Well the butcher told her there was no such cut of meat. Well she called me and  ..  this is what I sent her.

Looks like a flank to me!! So here is the question... Are cuts of meat regional?  Hmm Food for Thought!
