Yes. In case anyone isn't familiar, airline people have two varieties of recurrent sim training: Proficiency Check (PC) and Proficiency Training (PT).

A PC is like your original checkride. It has set requirements, is somewhat scripted, and can be failed.

A PT allows the instructor leeway to do different things, including multiple systems failures (which are not normally part of a PC). Technically, you cannot fail a PT, but if you do poorly enough, the instructor can usually stop the PT, and immediately commence a PC, which you can fail.

Normally you will alternate PC's and PT's, so a CA would see one PC and one PT each year at six month intervals, while an FO would see one of each every 24 months, at 12 month intervals. You must have a PC every 12 months (CA) or 24 Months (FO), but a PT can be replaced by a PC (there are several reasons for doing this). So you could have two PC's in a row, but never two PT's in a row.
