Yes, you're absolutely right---I forgot about that tactic.

"If you want to get around this, either because you are determined to use precise coords that aren't suprathreshold, or because of a paucity of suprathreshold voxels, I don't know of any way to do it other than playing with the SPM code, unfortunately."
To get around this (fixing the point), it is possible to lower the threshold - say by setting p value to be 0.1 or so. Still, if this region has generally "decreased" activation - this will not help.
