It doesn't. Wherever you got that from is a big sack of lies.

"Nullify all abilities of originally size 2 or less monsters in battle with that 《Neodragon》."

The key words being "in battle". Once the battle is over between the Neodragon and the opponent's monster, the opponent's monster will regain all abilities it had before the battle.

Note that abilities like Double Attack can activate as they take place after the battle has ended.
