I agree. Usually, if I talked about a 2" finished half square triangle, it is the finished side of the triangle and NOT the diagonal edge. BUT you have to be careful remembering to ask the quilters if that is the finished or unfinished size. I have no ideal what the diagonal edge of an unfinished 2.5 measures.
