Gdaddy, that video about box pressing presents an interesting take on an explanation. The compressions of the filler, rather than the actual shape of the cigar cross-section. May be true.
My sense is that the square profile (square cross-section) alters the flow of air and heat within the cigar--a result of the flow turbulence characteristics of a square nozzle vs. a round nozzle, so that the tobacco is actually burning differently in a box-pressed cigar.
A similar effect seems to happen when smoking pipe tobacco that is packed into the pipe as slightly broken or folded coins, compared to a uniform shred. The burn is slower, and the flavor seems more full.
I'm just guessing at this.
