A lot of the USGS products with Venus are a mess. From reprojection artifact filled maps to maps with misaligned stripes of data to uncredited Venera data.

It's a mess indeed. I don't know what bearing this has on the conclusions of the paper, but it certainly looks like the data is not in a good state.
Blink gif attached.

It seems like forcing the three main features below and to the left of center to correspond in the two images would require a significant re-projection. If the "expanded" caldera is a widening of the original one, it's hard to interpret in which direction(s) it expanded.

FWIW, the paper's 2nd author, Dr Hensley, isn't a SAR noob. He developed SRTM's strip image processor (and I think Cassini's too).
Honestly, when I saw his name on the paper, I was a bit disappointed the result wasn't found by reprocessing the raw signal data.
