I think that is almost total speculation, seeing as a rider on a brooks can have a +/- of a fair few mm of movement
first full of post on a horizontal tt bike - a rule as old as the hills! you can get a away with a little more or less but too much and it starts looking a mtb from the 90's
pet hate of mine when you see these custom bikes with odd seat post heights, ugly layback posts when it could be corrected in the frame design or too many headset spacers
no issue on everyday bikes but why spend 1k+ when you could have bought an OTP? the answer is more money than sense or a newbie imho
if however this particular bike is an exception and for some elaborate medical or personal reason the owner has to have more than normal seat post showing then fine - but for me it's no longer an admirable build
