The basic rule is that shafts are constrained at one end only. An ac bearing would only restrain in one direction; it could become either heavily loaded or so unloaded that it was loose.
Anchoring the crank at the flywheel seems more correct. Some other makes did.(And plain ball races are cheaper) However cranks in normal use usually fail from the inside radius outward so clutch loading presumably not a factor .
Some arrangement to positively locate on both crank and in housing necessary.
Anchoring at the front may benefit the timing gears.
