The printed text says '3 sols.'.

3.1.1... is a numerical representation of the solution tree (solution
tree starts with 3 branches, each of these has 1 level-2 sub-branch,
each level-2 sub-branch has one level-3 sub-branch, etc). So IMO, this
notation is correct even with AP problems (the solution tree has 3
starting branches, each of which is validated in a later sub-branch).
The notation doesn't imply that all solutions are possible at the same
time in the begin-position.
