Yes, that is correct, they are adopting PumaPay's payment system so that they can offer cryptopayments.
From the article about Ikajo's commitment, which you'll find posted just beneath this post:
"PumaPay, the blockchain-based payment system, has announced that global payment service provider, Ikajo International, will be adopting its cryptopayment solution."
But what the benefits in this for pumapay if they have own crypto-currency payment? PMA tokens will be not used in their system. And there is only benefits for Ikajo...
When they use PumaPay platform, this is beneficial for PumaPay. More people that use the platform the better.
