The origin of the relativistic Sagnac effect remains debated, particularly from the perspective of a rotating observer. Experimental results by Wang et al. (2003, 2004) have challenged the central role of platform rotation, prompting alternative explanations that attribute the effect to the relative motion between the observer and the reflectors guiding light along a closed path. We revisit the foundational concepts and existing relativistic formulations, highlighting their limitations. Through a thought experiment on the linear Sagnac effect and a reexamination of a previous proposal, we argue that the effect arises not from frame rotation or source-observer motion, but purely from the observer's asymmetric position relative to the light paths. This conclusion is further supported by an analysis of a rotational gedanken experiment.
