android.experimental.testOptions.managedDevices.maxConcurrentDevices=1 should result in the behavior that no more than one device is active at a time.

However, this is not the case: when the tests are running, many devices are spun up to run concurrently. In local testing, I've seen as many as 8 trying to be run at the same time.

When briefly debugging, it looks like the lock for the device count while running the tests is not kept while the tests are actually running:

The use does not extend to the call to runUtpWithRetryForEmulatorTimeoutException, which looks to be what runs the tests:
