I'm having a brain fart at the moment - what was the diff between
flying the 270 radial upon crossing the VOR and turning 270 upon
crossing?


I wondered that. It makes a diff if there is a significant wind from
the N or S, but he did say "very calm"!


Here's a guess.

I don't remember what direction he was coming from, but let's say it
was from the south in perfectly calm winds. If he waited until the
flag flipped then turned left to 270 in a rate one, he would end up
maybe a mile to the north of the 270 radial flying parallel to it
(assuming that VOR twist was the same as magvar). To intercept the
radial quickly after station passage, he'd probably need to turn to a
heading of 255 or so until the CDI centred.


All the best,


David
