Coel. Unchained Melody - new growth question

[WhiteRabbit]

I got a Coel. Unchained Melody in May - my first, and thus far only, Coel., so it's all new to me!

When I got the plant, it had a spike on it (no buds showing), which aborted shortly afterwards, and a small new growth starting. Not long after, it started another new growth, both are now mature. A couple of months ago, it started two more new growths, which are still fairly small.

I found small new nubs on the matured new growths a couple of days ago - Is it typical for these to start new growth at this time of year? If so, should plant still be kept on the drier side over winter, if it's growing?

Thanks for your help!
