Of course it's different!
If you listen to the two discs in succession with album gain or RG
disabled you wouldn't notice any loudness difference between disc one
and disc two because there is hardly any (track gain -7.71 dB vs. -7.11
dB).

With album gain per disc ("your way") track 1 on disc 2 will play 2.72
dB louder (disc gain -8.05 dB vs. -5.33 dB)!

What other tracks? 
The loudness difference between successive tracks is the same no matter
what method of album gain you use.
The whole point of album gain is to preserve loudness differences
between tracks on an album. 

Suppose we have an album that starts very loud and gets quieter and
quieter until the end.
single disc, 10 tracks, track gain -10 dB for track 1, -1 dB for track
10
album gain would be about -5.5 dB.
It's a single disc album so you and I will get the same album gain if
you don't decide to split the disc into subsets ;-)
We are likely to turn up the volume as the music gets quieter but hey,
we've decided on using album gain to preserve loudness differences
between tracks.

Now, if the same album was too long to fit on one disc.
Tracks 1-8 on disc 1, tracks 9,10 on disc 2
I still get an album gain of -5.5 dB and probably turn up the volume at
some point.

You will get a disc gain of -6.5 dB for disc 1 and -1.5 dB for disc 2.
When you play back the two discs in succession you will turn up the
volume at some point on disc 1. Track 9 will make you jump out of your
seat.

Loudness differences between successive tracks are far more annoying
because they are more easily perceived. The same loudness difference
over the course of several tracks might not be noticable at all because
our brain gradually adjusts to the situation.

What intent?
Can you provide a real world example where I would make more volume
knob adjustments than you? So far your claim is only a bold statement.
