Door seal question!

Hi everyone,
I've ordered the T moulding for our custom doors, and I'm wondering about which seal to buy. They have one that is made to fit in the T, but every video I've watched people use the rounded seal. The round seal makes logical sense to me, and I'm having a hard time wrapping my head around how the T seal will compress. I've attached a picture of these 2 seals for reference.
Thanks,
Nicole
