to be clearer, Short-Undo removes the latest overdub from the time that 
Undo was pressed,
to the "beginning" of the loop .

so if you record a phrase, and hit a wrong note at the end, you can hit
Short-Undo just before the last  note, and erase only that note

so your  case, hitting Short Undo between the 2 overdubs you just made 
would just erase
the second one

If you use Multiply (with Quantise=OFF) for just one loop to add your 
overdubs  then
you can overdub over exactly one loop, and redefine the Loop Start Point
at the same time.
Then you can always get rid of that "overdub" with one Long-Undo
