No what he means is although the females retain sperm for fertilizing her eggs it is best to let them breed again once a month during the breeding season, that way she is getting fresh sperm which would be more potent and better for fertlizing the eggs.
So when you go to breed next season introduce your male to your female let them breed I would let them stay together for a couple days. Then take him out. 3-4 weeks later introduce him again for a couple days and then again 3-4 weeks after that and do that for the entire season. My season runs from January-August so I introduce my males to my females once a month.
Another option is to let them live together and let nature take it's course. I have a pair that live together and have since I got them and I just let them breed on their own.
Hope this has helped.
