Probably because it would confuse the narrative, we've already seen Belkar is definitely affected but if Belkar was dead in some scenes, alive in others it would lead to a lot of people asking what was going on.
The first thing I thought is this felt like a filler strip, surely one double length comic is enough to explain they've been held by this trap. When it occurred this could be Elan's happy ending I started to worry about exactly what could give this strip enough significance to be included in the main arc?
Can't be good.
