There's chance for either...I have lopped and then gotten a second flower stalk but more times than not, I've gotten offsets. So it's hopeful and since you lopped two, maybe one will have offsets? Do not know whether certain cultivars have a tendency towards one more than the other in outcome.

"He (Howard Wills) noted that to encourage even more offshoots you may remove the monocarpic flowers, which usually appear in the second or third year of a plant’s life." Now, Howard has had years and years of growing sempervivum experience...
