This is hardcoded in align_image_stack, it has the equivalent to 
these hugin settings:

Local search area width: 100 pixels
Patch width: 20 pixels

..so my guess is that it will find points with ± 40 pixels 
displacement (untested).  I'm not sure that rotation search is 
enabled so probably any rotation over 10° will result in 
significantly less matches too.

Though recent versions downscale the image to 50% then divide it up 
into a 5x5 grid - this has the potential to reduce the number of 
matches with large displacement images, so I would try changing the 
grid size (ie. add a '-g 2' parameter to align_image_stack) and see 
if that makes any difference.
