Yes, I use a seperate decoder on the second receiver of my FT5000. 
Actually, I have 3 decoders going, I use a version of MMTTY and a 
version of 2 Tone to decode my main receiver. Most of the time, they 
both decode OK but with fluttery signals, QRN, QRM, etc. one will decode 
and the other will not. Just my estimate but 2 tone seems to win 9 out 
of 10 times when there is noise. I went to these two decoders on the 
main RX because I was noticing that, occasionally, the station I was 
working seemed to get my call wrong. Actually, I found out by adding 2 
tone to the main RX, that they were sending my call correctly but my 
version of MMTTY was decoding it wrong. Some common iterations of a bad 
call for me are W6GKC and W6RKN and of course, the always common W6RK. 
GKC and RKN occur quite a bit though. So by looking at 2 tone's 
decoding, if I see W6RKC in that window, I know they have my call OK and 
I do not have to go into gyrations to try and get them to correct it.

In split DXpedition operation, when they call a station, I start tuning 
the second receiver until I see the call of the station being worked or 
599 ( unshifted TOO also) or 73 on the screen. By zero beating that 
signal, it is pretty easy to be the next person in their log, especially 
with a small pileup and the DX listening up 1 to 2Khz. Of course, with 
the super wide splits of K1N, it took a bit more time to zero in on the 
called station. I use MMTTY to decode these signals on the second RX. I 
have a RF Space SDR-IQ receiver hooked up to the IF out on the FT5K as a 
panadapter but I find it distracting. The Yaesu SM-5000 station monitor 
is one step above useless. You can tell if 10 or 12 meters is open by 
seeing a signal or two but beyond that, it is not worth watching.

YMMV,

73,

Rick, W6RKC
