A ton of places are doing that. Restaurants that want to price things differently from their main. Or primarily in-store restaurant chains that don't want branding impacted by crappy delivery reviews. Keyword competition to improve sales. Menu, naming, picture, process experimentation. Additional placement in search results with different ranking. Bad review evasion. Limiting blast radius of bad reviews (eg, they still have a second high-rated listing for those X months they get less orders until a spat of negative reviews expire).
Basically, 'cheating' because it's not very honest, or can also be putting in extra effort to sell more and/or limit risk.
