Is it ok to add tolerance for snap points?

I made a change like this if you don't mind

def pick_point_to_move(x, y, view) 
    tolerance = 1000 # Tolerans değeri, piksel cinsinden
    @old_pt_to_move = @pt_to_move
    ph = view.pick_helper
    @selection = ph.pick_segment @pts, x, y

    if @selection
        if @selection < 0
            # Segment üzerinde bir nokta bulduysak
            pickray = view.pickray x, y
            i = -@selection
            segment = [@pts[i-1], @pts[i]]
            result = Geom.closest_points(segment, pickray)

            # Yakınlık kontrolü
            if result[0].distance(@pts[i-1]) <= tolerance || result[0].distance(@pts[i]) <= tolerance
                @pt_to_move = result[0]
            else
                @pt_to_move = nil
            end
        else
            # Kontrol noktasını bulduysak
            @pt_to_move = @pts[@selection]
        end
    else
        @pt_to_move = nil
    end
    @old_pt_to_move != @pt_to_move
end
