It will depend on where is the softest resistance, and if Russians want a cauldron where they can destroy Ukrainian troops and equipment, slowing the rate for Ukraine to prepare another offensive. They might want to close the gap more.
In Bakhmut they were also forced into the town to fight there for Ukrainians used the urban warfare to grind Russian troops down too. There was the undecided question that for which side was Bakhmut more of a trap. I think we can say for the Ukrainians, they wasted more resources, while the less concentration elsewhere allowed Russians to build their defense lines in relative peace, and the Ukrainian offensive fist got to be weaker than it should have. While Russians lost trained professionals there, like paratroopers, most of their losses were from the prison population volunteered in Wagner. And their material loss was even more negligible (lots of ammo and old equipment from warehouses).
In case of Avdiivka perhaps it's more clear that it will be a trap for Ukraine (again).
