Simple carpet question

[KevinK7]

I just received my ACC carpet, it looks great (80/20 loop w/mass backing)

I was a bit surprised to see it hemmed around all sides, more specifically being hemmed where it will go under the sill plates. Truck came with a rubber mat, so I don't have original carpet to compare.
I'm hoping hemming is left intact when under sill plate, but wondering if it might need to be cut...?
I know I can figure it out when ready to install, but figured I'd ask now.

Thanks,
Kevin
