Yes, you can mount both filesystems which are created with separate MDS/OSS on a single fabric.
e.g. ) assume two filesystems (both filesystem name is 'lustre') are configured below.
FS1 - MDS/MGS:192.168.1.1 and OSS: 192.168.1.2
FS2 - MDS/MGS:192.168.1.11 and OSS: 192.168.1.12

You should be able to do on the client.
mount -t lustre 192.168.1.1 at o2ib:/lustre /lustre1
mount -t lustre 192.168.1.11 at o2ib:/lustre /lustre2

btw, even you configured two filesystems on same MDS/OSS by different filesystem name, you can mount both on the client.

Thanks
