Yup, if you can control their environments (lighting, heat, food intake, humidity) closely enough, then you can manipulate their conditions to enable breeding year-round. In the wild they'd naturally only mate in the Spring, so that hatchlings appear just as their major food source (baby rodents, lizards and birds) were readily available.
However, in a normal domestic home-based setup, you tend to lack that sort of control. You can start putting them together for mating in January/February, although you may not see any action for a few attempts if you go for the earlier end of the range.
Much advice in the Corn world isn't "right" or "wrong" (except the one about calcium sand being good for a Corn's skin!). Quite a lot of it is personal opinion based on - in some cases - many years of experience. You need to find what works for you and your Corn.
