A Transcription Seal?
No...
It should be some other ocular technique.
As he watched the golden sand spread from his feet and wrap around him, "Hada Ichiba" showed no intention of dodging. He merely stood quietly, looking at the fading eyes of the dead Fourth Kazekage, at the Eternal Mangekyo Sharingan pattern belonging to Uchiha Nobuhiko within them, while a calm thought surfaced in his mind.
Without a doubt, the Fourth Kazekage's eyes had been implanted with an ocular technique similar to the Transcription Seal. Of course, this technique should differ from the Transcription Seal. What was certain was that it was also an ocular technique.
Its manifestation resembled the Transcription Seal, and its trigger condition was likely activating upon contact with his Chakra. However, unlike the Transcription Seal, which generally stored Sharingan ocular techniques and required a Sharingan to be transcribed, a Transcription Seal required not only that the stored technique be a Sharingan ocular technique, but also that the Fourth Kazekage's eyes be Sharingan.
Clearly, the Fourth Kazekage's eyes were not Sharingan, nor did his brain possess the special Chakra unique to the Sharingan.
And the technique currently being used was clearly the Fourth Kazekage's own technique, not a Sharingan ocular technique.
It was evident that this technique, which activated automatically upon touching his Chakra, was not a Transcription Seal.

So Chiba did not bother trying to determine what technique it was. Perhaps
