The meme shows a reusable glass bottle (the same one I get my milk delivered in, actually). The study explicitly excludes reuse of the glass bottles and notes that they’ll generally get reused 20-40 times, reducing their impact.
The 1:1 comparison, at least where I live, is of single-use “recyclable” plastic to reusable glass bottles, which this study does not do.
The straw man to which OP is referring is the specific assumption that one is replacing single use plastic with single use glass, which is a much weaker statement than what my interpretation of OP’s meme was, which includes reusing the glass.
If OP had used a glass coke bottle (for which I can’t find the same evidence of reuse, and which do have much longer logistics chains, increasing the impact of the Glass’s weight), the interpretation of single use glass would be more reasonable.
