Each one would need to be looked at individually.
But in all cases they would need to be primed. A back up system for bud set then vernalization is vernalization of plants that are near maturity. This will set bud. I suspect that in many of these near maturity plants, that vernalization can be effective in an epigentic vernalization set. Then maturity, then bud set and instant bloom as every thing is lined up, but not in way it is designed. 

Best I can offer.

So what's the deal with Margie's irises that rebloom 6 weeks after
spring bloom?

Others (including Betty and I) have observed this some years.  Saw it
here one spring when cool temperatures persisted (or maybe returned
after a warm spell?).

Prince of Burgundy was the first one I saw do that here.  Years ago,
probably reported in the archives, so I could dig up weather records for 
that year.
