Can flash be used with electronic first curtain shutter?

yes, it is not a rolling electronic shutter.

How do you know that?

Read the rest of the thread and you'll know why.

Also, wouldn't that imply that it's a global shutter, albeit only with electronic first curtain?

Depends on exactly how you define "global". The precondition for flash to work is that the entire frame is being exposed when the flash fires. With the electronic first curtain shutter of the E-M1 that happens at any shutter speed where the EFCS can be used, i.e., up to 1/320 s. With the rolling electronic shutters available on Panasonic bodies, it happens only if you use a shutter speed slower than 1/10 s to 1/25 s depending on exactly which body we are talking about. At any speed higher than that, only part of the frame would be exposed when the flash fires.
