Absolutely, aerobraking is not an approved technique on the A320 series, try it in a 321 and you will scrape the tail, an A320 wont be pretty either.

The usual reason on the 320 series for a nose in the air is as described, a late, snatched flare which drives the mainwheels into the ground, the nose up from the flare input is stil active, this is compounded by the spoiler deployment which causes a further nose up input. It is something to be aware of and to guard against on the A320, indeed in a A321 should the pitch angle reach 7.5 degrees noseup the pilot monitoring calls a warning, as a tailscraoe is now highly likely should any further noseup attitude happen.
