IMO, only some factors would have to come into play to stack a reverse.

1. It does not breach the reverse funders contract.
2. There are less than 4 positions being consolidated
3. The amount being paid with an additional position is not waaay over their ability.
4. The broker does not intend to ***** the Merchant out afterwards.

Reverse funders are no different than a funder that funds a merchant and pays off positions for them. They are just doing it in a smarter way if you think about it. More cashflow flexibility to fund more Merchants, smaller dollar amounts of disbursements, and preventing possible breaches or additional fees in paying off positions with specific funders directly.
