Signing out of Apple ID/iCloud

No, sorry, you didn't. iCloud data is not device-specific, it is Apple/iCloud account-specific, so you would have to intentionally transfer data on the device to that iCloud account by merging it when you signed in. If you didn't merge anything, then nothing has been transferred to that iCloud account.

Is this a temporary sign on, or what? Because, although nothing will be merged from your device to the iCloud account you signed into (unless you told it to merge), the data on the iCloud account that you are signing in will download to that device if the option for that iCloud service is turned on under Settings>iCloud.

So, Contacts, Calendars, Reminders, Notes, etc. could all be downloaded if those options were turned on.

Not clear on where you are doing the signing in and out, but if you sign out of iCloud on your iOS device, you will be asked about keeping data on the device. You can choose to keep the data on the device then merge it with the new iCloud account that you sign in, or you can keep it on the device and not merge it, or you can just not keep it on the device.

Some iCloud data (like Notes, iCloud Drive (Files), Photos) will simply be removed from the device and will not be accessible.

If you said not to merge your data when you signed in the second iCloud account, then nothing was merged with that second account, so it wouldn't have any of your data.
