Look at these insignificant gains, in all of June Putin managed to add 50km2, that's 0.01%, of new occupied territory, now compare that to the unsustainable colossal losses of Russian troops and material.
Keep in mind that Putn started his second invasion already occupying about 9% of Ukraine.
"Indisputable", right, hilarious.
The map of Russia's occupation has looked essentially identical to this. If you zoom in real close, like really really close, you'd see all that "Russian momentum".
