I think the concern is that the reader might pick up a different payment form than the one you intend on using if there are multiple in close proximity. I highly doubt it will charge multiple times, as the sort of interlock you are describing is pretty standard NFC stuff. Using the same form of payment as you make transfers is needed to make sure you aren't charged extra.
