NFC switches help

view story

http://forums.androidcentral.com – I've seen it's possible to create a switch (two separate groups of action on the same tag) so for example I can have a tag on the door of my house that with the first pass activate wifi and with the second deactivate it. My question is waht happens if between the the two passes I use a second tag (a simple one or one with a switch)? When I pass again on the first tag, what action will be executed (the enter or the exit task). I hope it's clear enough to get an answer. Thanks in advance for your time/help. :) (HowTos)
