That is correct - at least up to a certain point in time as these things are just developing they look very similar. But what's more important is what to do about these things. How would you deal with one of the crashes you mention differently from one of the bear markets you mention?
If Rocket Man drops a nuke on Guam or Hawaii tomorrow and the market drops 10-20% or more, that's a crash and your Dow vs 50 EMA was worthless. As I said in the post that you replied to, unless you had some form of negative correlation protection in place prior to a crash, you took the hit (long puts, collars, etc.).
For a bear, again, as I posted previously, I'd do as I did in 2008 and transition from long to short. To be honest, I didn't do that exactly. I unloaded the bulk of my long positions by Dec '07 and then ran a long/short correlation portfolio biased to the short side for 18 months - so I was net short most of that time.
