Hi KeithŠ

Assuming it's on two different interfaces on your side then it doesn't
matter (for layer3 interfaces).  On their side, it's best to ask them as
you want to ensure that the layer2 paths are kept separateŠ assuming they
are running this to two different routers (or even interfaces) then it
probably wouldn't cause issues.
