I don't think it was intentional.
After the PekoMoona Turing Love released Moona said she asked REDSHiFT if he would do their cover only for him to cancel a few days later saying he would be too busy with other projects for how little she was willing to pay so she had to go with a lesser known more amateur producer, which definitely showed in the end result so she was a bit apologetic and depressed about it.
Then around the same time as their cover released Reine started releasing one REDSHiFT produced cover after the next, so it's pretty likely she just offered him a lot more than Moona.
Considering how autistic Moona is it's not exactly unlikely that Reine didn't even know about her trying to get REDSHiFT though, I really wouldn't blame her for anything either way though, it just is what it is.
