Only until end of March 2019 -- after that it will be extra $$$

Short Answer - Yes it can happen -- but since you have flown UA before, it is not a regular event.
Longer answer -- see this thread
With the reconfigured planes there is a lot of seat shuffling as configurations get swapped in and out
Interim 77x seatmaps with Polaris seats & potentially Premium Economy (2018-19))

Not done in economy
There are special contractual issues for premium cabin seating for pilots -- but rare to actually move a passenger.

Disable passenger -- because only select E+ seats -- such as bulkheads are appropriate depending on the disability.
FAM -- by federal regulation, the FAM selects the seat and UA must move the passenger if the seat was assigned. The airline has no choice in the matter.
