[On Radioddity GM-30, what is the purpose of tone settings on a repeater frequency (ex: 467.675) in VFO mode?]

Using Radioddity GM-30.

On a GMRS repeater Ch 6:   Rx 462.675 / Tx 467.675,   it is obvious what the  CTCSS and DCS do.

Tx tone is for transmitting to repeater on 467.675.  Rx is for receiving on 462.675

What is use of setting an Rx tone on 467.675 in the VFO mode?  Is it to receive transmissions intended for a repeater?

What is use of setting an Tx tone on 467.675 in the VFO mode, since the radio can't transmit in VFO mode? Or does it set the Tx tone when in channel mode on Ch6?
