I don't think it's as simple as "Chase shall buy ____ miles from United Airlines for $______".

If Chase is satisfied with the purchase volume on the cards, then the extra revenue and lower fraud liability may not be sufficient to justify the costs of conversion at this time. Similarly, if UA is satisfied with the number of miles Chase is buying and the price, they may not be bothered either.
