I think it's quite a rare problem to accidentally switch gods. More often people accidentally pray at an altar while running and praying but it's something I'd consider a problem for the individual. Most know where altars are, they're quite clearly visible so any attentive player would have no problem avoiding the altar while praying (there are so many other places you can pray would you believe).

My advise to people would be to be attentive, you obviously know the god you're allied with (you can check through /skills), so there shouldn't be any unfortunate incidents like this.
