Volume Loop- Gigrig Humdinger (this is splitting the signal. Send from volume loop to Humdinger, Isolated out of humdinger to dry amp, buffered output of humdinger to volume return of es8) The volume loop is placed after loop 6 and before loop 7 in the chain so that the dry signal SHOULD only be going to the dry amp and the H90 SHOULD only be outputting the signal from itself and not the prior gain stages.
If the H90 is set to Killy Dry ON, then what you say is correct, though the H90 will be receiving the prior gain stage at its input.

Fuzzes do not like to see buffers before their inputs. The ES-8 is notorious for using input and output buffers as well as the individual loops. This is what I’m referring to.
