E-Lux inboard/outboard

I think that the main reason for the usage on outboard clutch by Husq/Jons is not the bearings, but the reality that the crankcase is the most complicated detail of chainsaw, the replacement of outboard design with the inboard clutch demands completely new crankcase, which is expencive to design, etc.
Jugs-pistons are easy to redesign for new saws
I think you are on the track of something, and so was bwalker in the post you quoted. But I think the picture is a bit more complicated.
I could be wrong, but here we go;
Originally Husky, Jred and Partner had a tradition for outboard clutches. As far as I know the first E-Lux saw to have it inboard was the P7700 from about 1983/84. That saw was developed into the Jred 2077, 2083 and 2083 II - and several Poulan Pro models (475, 505 and a 65 cc version as I recall).
The 94 cc Husky/Jreds and the 3120 was developed before the Husky/Jred tradition started to budge - and therefore has outboard clutches.
The
sideways balance with long and heavy bars could also be a factor.
The 371 family of saws, that is now 372, 2171 etc, was developed a bit later, and they got the inboard clutch. Probably because they had admitted that it was the best solution at that time. The 385/2186 was even later, and also got it.
On the smaller saws, the outboard clutches are probably a trade-off, to be able to make the slim saw bodies they brag about in advertisement.
The slim bodies sure
are nice, so it is really up to the costumer to decide if it is worth the trade-off, or not.
