How do I get both Calyrex rider forms at the same time?

I’m asking this question as I ran into two people in multi-battles earlier last night with both Calyrex rider forms on their teams, the Nick guy had a Green colored Keldeo Resolute Form icon and the Top Shotta guy had a Yellow colored Hoopa Unbound Icon.

Though the game will not let me fuse another Calyrex again using the reins of unity after I’ve already fused the Calyrex from my first play through from Sword/Shield with Spectrier. It only lets me fuse again when I unfuse my Calyrex and Spectrier. And I can’t transfer Ice Rider to HOME to put into my game of Scarlet/Violet. So how do I get both Calyrex Shadow Rider and Ice Rider at the same time to be on the same team like these two did?

You can’t.

Once a Calyrex is fused with a steed, your second specimen can’t fuse with a steed. You can only have 1 Rider Calyrex at the same time.

This combined with the fact that a fused Calyrexcannot be traded, released, or sent to HOME,proves that it is impossible to have two fused Calyrex in one game without hacking.

These properties are all shared with Black/White Kyurem as well as Dusk Mane/Dawn Wings Necrozma.
