Yes, that is correct. (The SBRef for the BOLD scans are gradient-echo images).

After reading the preprocessing scripts (see https://github.com/Washington-University/Pipelines/blob/master/fMRIVolume/scripts/DistortionCorrectionAndEPIToT1wReg_FLIRTBBRAndFreeSurferBBRbased.sh#L271)
and the paper (see http://www.sciencedirect.com/science/article/pii/S1053811913005053) I figured that HCP is using a pair of spin-echo EPI scans to estimate a fieldmap later used
to correct fMRI data for distortions (in contrast to using a pair of SBRef images). We had a bit of a discussion in the lab about this and I just wanted someone from the HCP team to confirm this. Thanks in advance!
Best,
Chris
