He's expecting to be jumped sooner or later--Reyes always one-upped him in this department, and he hasn't forgotten the quips about being predictable. There's always a small part of him that knows he won't be able to outdo Gabriel at his own game, but it doesn't stop him from trying anyway.

All he can do is keep his ears out for the inevitable and hope that his visor picks Reaper up fast enough once he's re-materalized.

And the blip does come back, though he can't be sure whether or not he's been spotted in the interim. The more steps he takes, however, the more he becomes certain that he's walking right into an ambush. He's not going to give Reaper the satisfaction.

I know you're there.
