There's no special handling of legato on the keyboard's side. The second note will be on a different channel. An MPE instrument would just ignore the channel information for the legato decision. If notes overlap - no matter the channel - do legato.
This means, if you create a bunch of instruments to make a fake MPE instrument, the legato decision of that instrument cluster is not working (without some clever processing of the MIDI stream). Most legato instruments are monophonic, so for these I just reduce the channels sent by the Seaboard to a single one. For instruments with "poly legato" (eg some guitar vsti with legato per string) I haven't found a satisfying solution.
That's true for ROLI. Linnstrument possibly is different, because it can handle its rows akin to guitar strings, so it maybe does send (I haven't played one): same row -> same channel.
