The threat of intervention from Belarus, or a new offensive near Kharkiv, is probably better for Russia than any actual invasion from there. 

Russia is on the back foot in Kherson and Donetsk, if Russia has quality reserves they should be used to stop their current losses and open up the Lyman encirclement, rather than open a new front. Starting a new offensive in a completely different area would likely end just like their Kyiv thunder run, with a lot of dead Russians and blown up equipment in a short time. It's easier for Ukraine to move forces around on their interior lines than it is for Russia, and any gains an offensive would make would require further support to hold it, support they desperately need to be sending elsewhere. With all their best offensive troops tied down defending Kherson, I don't think it's very likely.

Ukraine may have to hold some forces back to guard against the possibility which is a plus for Russia, but if Russia tried it, would just hasten their eventual loss.
