How the condition works to have separate condition triggered?

Summary:

I have one requirement to add validation in field service. This requirement was to trigger two different validation, but as it is not feasible currently I am trying to give one user friendly validation which includes both the condition and validation message.

Requirement -

We have 3 forms i.e Take 5 form, Check in and check out form. When technician finishes there work they mark the reason to suspend is to Tech work complete.

We already have validation in place for Take 5 form that user cannot mark the activity as tech work complete until the take 5 form is filled it is for both branch and field service technician. But we want to have one more validation to prevent user from marking the activity as tech work complete until check out form is completed but this is only for branch technician. I tried below condition but with this take 5 complete condition is also not working for field service technician.
