SUMMARY


STEPS TO REPRODUCE
1. Activate Freehand Selection Tool (lasso)
2. Use it multiple times in Replace Mode with Shift modifier to add to the selection (using Shift to temporarily enable Add mode)
3. Now use Ctrl as a modifier when making a selection to enable Continuous Mode (Polygonal Selection mode) temporarily, getting some straight edges on the selection.
4. Try to use Ctrl to get straight edges and also use Shift to Add to the Selection multiple times (while the Freehand Selection tool is set to Replace in the Tool Options).

OBSERVED RESULT

Adding and Subtracting with Alt and Shift while using Ctrl to get straight edges with the Freehand Selection tool is impossible, while the tool is set to Replace mode in the Tool Options. This is likely because Ctrl is enables both the Continuous mode as well as Replace mode. So it doesn't let Shift and Alt enable Add or Subtract, maybe.

EXPECTED RESULT

One should be able to use Ctrl to get straight edged selections when necessary and hold Shift or Alt before releasing Ctrl to be able to Add or Subtract the selection.
