I didn't have my Z all last weekend, but I did have several chances to try and recreate your experience over the past several days. I think one time out of probably 50-60 shifts it did something very similar to your video. I don't know that your experience is normal, but it seems that it's not completely out of the ordinary.

I tried all sorts of speeds in shifting, pauses, and even some double clutching in my testing. The SRM response varied slightly depending on my input. Earlier I said that SRM should be extremely consistent. This is true, but only when all the variables are the same. Since the input is changing constantly, it's difficult to recreate the exact circumstances every time. It seemed that minor variances in speed at the time of or acceleration/deceleration prior to shifting would alter the SRM response slightly. Also, the speed of the shift and any pauses in the motion can affect what SRM thinks you are trying to do. I did find it very difficult to set off the 3rd gear gate sensor without a full 1K jump in revs, and it did not seem like 'brushing' against it on the 4-5 shift should ever trigger SRM to think you were going to 3rd gear.

The only suggestion I have is to check the alignment of the shifter assembly. Although, if you are completely stock, I don't see why that would be an issue. Plus it's not uncommon for Nissan to use so much locktite that you have to tear up the stock shift knob to get it off. Not good if you don't have a replacement ready and waiting.
