MPM82504 max with active current sharing

I have a question regarding the MPM82504.

According to the datasheet, the maximum number of MPM82504 devices that can be connected in parallel appears to be limited to 3 (p57).

Could you please confirm whether this is a strict limitation, or if it is possible to parallel more than 3 devices while maintaining active current sharing?

If more than 3 devices are supported, what would be the maximum number of devices allowed in a single current-sharing group?

Thank you for your help.
