The right one is 4-connected, the left one is 8-connected.
IJ natively supports 8-connected regions.

You can analyse 4-connected regions using  the Particles4 plugin, but before
jumping into that, please make sure that you understand the implications of
changing the connectivity of your regions.

Cheers
