Pay close attention to the wording of the contract. It could be double-dipping if there is a contract stipulation with one of the MSCs or clients that you cannot have visited or audited this theatre in x amount of time. If this is a blind (unrevealed) trailer check, the MSCs will also be concerned about you being identified as a checker. It's very hard to walk in and out of a theatre multiple times in the same day and not have the employees at least suspect that something is up. I would never accept both assignments if at least one trailer check is supposed to be blind UNLESS the revealed one can start after the blind one is finished.
If there isn't any mention of a rotation, you are probably free to complete both as long as one does not conflict with completing the other. Also, if you do this, make as sure as you can that none of the times for the trailers you are supposed to check will overlap. Sometimes, films start on multiple screens and/or within just a few minutes of each other. If you are supposed to watch Trailer Set A, which lasts 10 minutes, and Trailer Set B starts 5 minutes into Trailer Set A, then you might not be able to get the information you need, and you are not allowed to ask theater employees or customers what was shown. Some MSCs will allow you to work with a partner in cases where trailer times overlap, but if there's a check for which you absolutely have to go alone and there is a scheduling conflict with trailer times, then you could be screwed.
Additionally, revealing yourself for an open check may possibly mean that you either can't or might have to wait a longer time to do blind checks again in that theater. It would be up to the MSCs and clients.
