There might well be other factors—offhand I can think of setting a precedent for “negotiating” after an invasion, and gaining a stable advantage from having the territory (so the loss of the army during the invasion will have been worth it).
Depends on what’s on that 1% of the territory, and whether it allows me to take over the entire country in the future, for example. (I do hope Putin will lose 90% of his army at some point.)

Numbers matter. Losing 90% of your army to gain 1% territory does not seem worth it.
