That's not true (unless we're talking about bombardment battles with more than 10 range units on each side and no fortress involved - then it's totally clear the one who splits up wins - so this thread definitely is not about such battles, only about all others
Assuming 10 strongest units have the same damage output values in each of the three stacks (which by the way is more difficult to achieve with the two smaller stacks). Then the 50-unit stacks swallows twice as much damage per hour as each of the two 25-unit stacks do. But has twice the HP compared to each of the 25-unit stacks. So all three stacks will be down to 50% health at about the same time. Afterwards the 50-unit stack will win, because it happens earlier that one of the 10 strongest units in the smaller stacks dies.
Your description is correct for cases where the big army is defending only (and consisting of more defense-focused units). I can absolutely vouch for my statement being true for fights where the single army is attacking or attacking+defending, due to how damage in multi-army fights is distributed. I also tested it in practice and can confirm it.
Here is my setup:
Allied Doctrine for both players
The same 50 units for both players
Player A army 1: (A1)
20 Inf lvl1, 15 armored cars lvl1, 15 light tanks lvl1 (see picture 1)
Player B army 1: (B1)
10 Inf lvl1, 7 armored cars lvl1, 8 light tanks lvl1 (see picture 2)
Player B army 2: (B2)
10 Inf lvl1, 8 armored cars lvl1, 7 light tanks lvl1
All armies had 100% condition (first picture is already after first combat round).
All armies meet up on conquered terrain, so no home defense bonus for either army.
All armies are in movement, so all armies are attacking and defending at the same time. (note: I gave the movement order to army A1 with a bit of a delay, so the attack tick of army B happens before the attack tick of army A1 in the pictures. Since the stacks consist of more defensive units than offensive this is actually favourable to army A1)
After several ticks, army A1 was down to 29 units at 34% condition (see picture 3), while army B1 and B2 had 22 and 23 units, at 47% and 49%. (see picture 4)
After the battle was over, army A1 was dead and army B1 and B2 survived with 21 units each, at 36% and 38% condition (see picture 5), so after combining them back to one army 42 surviving units at 37% condition (see picture 6).
The 2 split armies combined just deal out more damage per round due to not wasting as much damage efficiency, so it doesnt matter if the single army has more hitpoints than one of the split armies, incoming attack damage is shared between the 2 (area damage) while they both return their full defense damage.
This is only the case though when the single army is attacking or attacking+defending. If it is defending only and doesnt have more attacking-focused units in it, it is not at a disadvantage anymore. In such a case your statement would be true (but I feel like most players drive around carelessly with their mega stack, being most often on the attacking side of things).
If more people knew about this, we would probably see less large stacks. But I guess there is still this myth going around that a single stack is stronger. Hopefully the new army bar layout will help highlighting the loss in efficiency of big stacks.
In case anyone is wondering how you can prevent your 2 melee armies from merging: Just give them different orders.
Attached are some images for the combat that I just mentioned
