Two waste pipes in the small bathroom, going to the same outdoor pipe

Just wondered if you could answer this question for me please, sink on one side of the small bathroom with original outlet pipe. This pipe was used for the old existing shower cubicle. Opposite shower replaced with new bath with its own outlet pipe, the plumber core drilled through 16" of stone to fit pipe it feeds to same out door pipe as sink ( hence now I have two outlet pipes) I've got wooden floor could the plumber have fed the bath pipe to the sink pipe, like it was done originally with the shower, and why did he not put the waste pipe from the sink under the floor board it's a white visible pipe on the surface (ugly will need to be boxed in)
