I think it's not as much "if this guy becomes the lead I'm immediately quitting my Ruby job to return to PHP" as much as "if this guy becomes the lead I'm probably going to return to PHP for my next job."
I have my doubts, even for this softer version. These are things where one might feel very strongly in a moment, or even for a longer time, but facing a real life decision, there are so many other factors.
Of course we will never know the outcome of this, it's just my two cents.
