They are separate paths and then summed when at the master out (in my experience)

Tracks that get sent to the AUX (with FX) get sent to the Main OUT. But so does the original track output (with or without FX)
Subgroups also get sent to the Main Out and get joined with AUX and other track sends (those not in the subgroup) but the tracks go to the subgroup first before being sent along to the main out.

The difference is an AUX send 'Adds' the effect to the original track (which the AUX receives dry), which then gets sent to the main out in addition to the original track's output.
When using Subgroups, the tracks go to the subgroup first (with any FX added) and then sent to the main out (so they intercept the track, affect it, and send it on its way). In other words one is a parallel path, the other is a linear path for the original Track output.

At least that is how I understand it works.

With an Aux path both the Track and AUX go there as separate entities.
With subgroups, the track(s) in the subgroup go to the subgroup first before being sent to the main out.
