I don't believe there is any real difference between "holding globe close to body" and "holding globe across body".
Lech says the same thing on his p.389 notes:
https://www.forumancientcoins.com/notInRic/cv6.htmlI think in cases like this there may have been some very minor difference between specimens - same basic arm bent, elbow out pose, holding globe close to body, but in one case really close to body, and in another with a slight gap. It's probably a result of recording the coins, without photographs to go back and compare, before they had seen enough coins to realize the big picture and properly determine the "multiple choice" categories.
The RIC 339 & 340 listings reference specimens in Vienna which unfortunately they don't have online, but it's possible they may give a photo if you ask (Lech has been successful before, but maybe because of his famous Not In RIC site). I'd bet the Vienna specimens look the same as all the others!
