Well, that's a side-effect of the temporal processing. (There often is a positive effect on dotcrawl, but it's not a specialised feature --> "YMMV").
The main point of that small comparison is instability & flickering of the actual detail.

Just yesterday I played with a DVB cap of a 50i TV show, and compared TGMC with HW-deinterlacing via DGDecNV. No need to mention that TGMC was stable and NV-Bobbing was flickering. But another point was the encoded filesizes:

x264 @ CRF 18:

TGMC-bob: ~5100 kbps
NV-bob: ~9500 kbps

That is, HW deinterlacing required almost double the bitrate to encode something with noticeable lower quality.
