Forum:Card of Safe Return

According to the Tips section for De-Synchro, if you have Card of Safe Return on your field and you activate De-Synchro on your monster and Special Summon all of the Synchro Material Monsters, then you only draw one card, because it's one card per summoning effect. But, Card of Safe Return says "When a monster is Special Summoned...", so doesn't mean it's one card for each monster Special Summoned? If not, why didn't they ever specify this?
