Not trying to make you feel stupid or wave willy's at all, just establishing credentials as an aviator and not MS Flight Sim flyer.
I currently dont have to hand the entry procedures available but when I rejoin body with home I will have a go at digging them out.
The FMS will attempt to join the hold in 1 of the 3 standard ways (but can come up with an alternative to what you think if its within the 5 deg area).
Overall the ICAO joins are usual no matter where you are, my general point is that SOME aviators from FAA areas may not be aware of the ICAO only perspective of other aviation areas. (And vice versa)
