Redstone stays active after removing connection to a always-on repeater loop

I created a button which sends redstone signal to a repeater loop to always stay on like an RS NOR Latch (but without a reset) and from there I power 2 other repeaters facing to a block with redstone torches above to open closed iron doors. When I remove the connecting redstone from the "always-on repeaters" to the repeaters powering the torches the stay active. But they should be disabled?
