Does my student have to use the same computer for both CBT test sessions?

No, students can use multiple computer devices for CBT test sessions. The student should log out (i.e., submit the test answers or pause the test to log out) before logging into a different computer. 

Logging into a paused-student-test-session on a different computer will return the student to the point within the test where the student paused the test. Note that a Proctor PIN is necessary to log a student back into a paused test session. 

Multiple students can use the same device during a testing day as long as a student is individually logging in and out (i.e., submitting the test answers or pausing the test to log out) of a test session before a different student uses the same device for a new test session.
