BINS was designed to treat the interval from xmin to xmax on the real
number line as a CLOSED interval (where xmax = xmin + width * N).

Thus, it divides the interval into N-1 half-open intervals of the form
{x : xi <= x < xi+width} and 1 closed interval {x : xmax-width <= x <= xmax}.
xmax is included in the last interval.

Your example can be depicted as follows:

      [----)[----)[----]
1     2     3     4    5
     xmin             xmax


xmin=2, width=1, N=3, xmax=5, there is one value (1) which is less than xmin 
and no values which are greater than xmax.
