Possibly, but rather unlikely...

Can you also report the output of checkjob and diagnose -j on these 2
jobs? Do they also have the MEM requirement?

Well, it must be coming from somewhere, quite possibly from a default in
the queue or server configuration. So I'd try unsetting it there.
However, looking at the diagnose -n output above makes me think it is
processor related - judging from the 0:4, for some unknown reason your
jobs consume 2 processors each rather than 1.
