Is it possible to get 2 points in 1 year in WY?

If I try and draw in Jan (unsuccessfully) and get a point can I still buy a point in September? I am just trying to figure out what year I will have a reasonable chance of drawing my unit.
Right now I have 2 points. I plan to buy a point in Sep(now at 3), then try and draw in Jan again(probably unsuccessfully makes 4) then buy another in Sept(makes 5) then go into draw with 5 in January and hopefully draw.

Does this sound right?

Thanks in advance.
