RS485 network biasing question

User ColmR explained in other thread that RS485 specification is not dependent on the supply voltage of the tranceivers. Is that still valid if we consider a RS485 implementation with two nodes, one operating at 3V3 and other at 5V, with a biasing circuit (3 resistors scheme; pull-up tied do either 3V3 or 5V) in a given node of this network?
