That’s normal. Hells’ Xgress actions are not targeted, so if your target dies before you can face target you’re going to go the direction you were facing before you activated the macro. Or if you’re pressing a movement button, the movement button will reassert itself in the fraction of a second between facetarget and the Xgress action.

The Ingress and Egress actions would benefit from having an optional target but that’s not how they’re programmed right now.
