Ich can encyst for up to ... what is it, 72 days? Copper is only effective on free-swimming ich parasites, so if there are cysts on your glass/in your filter/in your PVC hidey-holes after 14 days, and you remove the copper but return the fish . . .
Even the two-week end-of-copper transfer to another QT, it seems to me, is something of a hybrid tank-transfer-method. You've waited until the ich parasites have all dropped off of the fish, and you're moving the fish to a parasite-free environment, rather than back into the tank they just came from.
