That was me. You are not supposed to massage the area vigorously because you can actually push the ester into surrounding adipose tissue which will later affect absorption.
I have learned this in my own medical training and have spoken with several fellow doctors who follow the practice themselves. I have also however, spoken with people who think such advice is as you put it, "ridiculous".
I am only giving you my own advice, just like when asked on a board, a person will give their best advice.
Take it or leave it...
