Let's say room 1 and 2 are adjoining rooms.
The hotel takes a booking for adjoining rooms 1 and 2 for Family Z checking in on January 3rd.
On January 1st Family X checks in to room 1 for 2 nights.
On January 1st Family Y checks in to room 2 for 2 nights.
Scenario 1: On the morning of January 3rd, Family X checks out. Family Y informs the front desk that they are going to extend their visit 2 more nights. The hotel is not sold out, so they can honor this.
However, if they had promised adjoining rooms to Family Z, the hotel would have to move Family Y who has been there for 2 nights already or fail to deliver on their guarantee.
Scenario 2: On the morning of January 3rd, both families check out as planned. Family Y informs the front desk that the toilet overflowed just prior to checking out. Housekeeping reports that the water has gotten to the carpet. The room will need some work before it is able to be occupied again.
Family Z arrives and has been promised adjoining rooms; however, one of the two rooms is not able to be used due to water damage. The hotel fails to deliver on their guarantee.
It's much easier for hotels to not guarantee adjoining rooms.
