This is the same design for MPC6e PFE and I didn't see any issue with this design. I also didn't see any specific issue due to this design in POC where we stressed the PFE. XL ressources are just shared. For Inter XM forwarding, the shared XL is not used but the fabric links is used.

Hi folks, Would anyone know what’s the story behind MPC5E (which I think uses one PFE) with Gen 2 TRIO (XM, XL)? Forwarding capability of up to 130 Gbps per Packet Forwarding Engine. Up to 240 Gbps of full-duplex traffic. - Since 240 is not 2x130 it begs the question what components are the
