Semen not in the condom reservoir

Hello!

So yesterday I had sex with my gf and as we always do , we used a condom. When I had orgasm I kept thrusting for about ~4-5s and then I immediately pulled out and I held the condom at the base. I saw that there was little semen in the reservoir and the rest of it was around my penis(inside the condom). To be precise everything was in the upper part of the penis , so no semen at the base of the condom.
Is this a cause of concern ? From my side everything is right , even though the semen was not in the reservoir as long as it was still inside the condom and no way near the shaft of the penis. What do you think? Thank you!
