I’m interpreting it a little different than mf_social. I think your first automation is set to trigger every second as long as the hour is 2. So between 2:00 and 3:00, your first automation would trigger every second.
I’d suggest you check the docs for automations, specifically the time trigger. I think what you are looking for is the example called ‘automation 3’, using an interval.
I think you could perhaps do with one automation, using a 10 seconds delay in the action part. Something like:

Time can be triggered in many ways. The most common is to specify at and trigger at a specific point in time each day. Alternatively, you can also match if the hour, minute or second of the current time has a specific value. You can prefix the value with a / to match whenever the value is divisible by that number.
