If they carefully read their own policy, they'd probably realize that while the idea was to a set new minimum amount for rentistas to demonstrate and for the first time set an amount for pensionistas, it was only intended that the rentistas actually deposit into an account here. The majority of the text is about upping the existing minimum amount for rentistas, who, historically, always had to bring the money in. Setting a minumum for pensionistas (who previously faced no minimum whatsoever, let alone an obligation to transfer it) is a kind of add on at the end of the text.
Still, it has been interpreted they way they are interpreting it, and we are stuck with it.
