You can only enter the portal from on side, so if you're using it for an ally it would mean that you are already in danger, since you're at the same place.

As Skyhero said, you can use your Q as they exit the portal for an easy stun. You can also use it to bait the enemy team or use your ult when they arrive, so it has upsides aswell. And let's not forget that your allies moves faster through the portal so depending on the lenght of the portal it can actually buy them a lot of time even if they enter it at the same time.
