"Pray to God for us"

I just read something online that gave me a realization: When certain Protestants hear us ask a Saint or the Theotokos to pray "for" us, do they hear "pray in place of us"???

What we mean is "pray concerning us." Just like intercessory prayer I know many Protestants are familiar with - and nothing like what might be called 'substitutionary prayer'??? Hence the comparison we offer to asking friends, relatives, neighbors, fellow parishioners, to pray concerning us or something we're concerned about...even to join us in prayer regarding this or that issue...even if it's not at the same time and place that we do our praying.
