The issue is that image- or GIF Ordinals can be easily downloaded and copied or used without permission, in other hand a Base64-encoded image cannot be easily downloaded.
Furthermore, this method allows for the creation of 3D models—such as cubes, spheres, or rotating cards—using HTML code, enabling multiple images to be displayed within a single, compressed Ordinal. Another advantage applies to webpage-style Ordinals that typically call upon separate image-based Ordinals for their content; with this technique, everything can be contained within a single inscription. However, a downside is that the same image cannot be reused across two different on-chain websites.
